Making your own reusable menstrual pads requires basic sewing skills, a few specific fabric types, and a straightforward pattern you can draft at home. The process takes roughly 30 to 45 minutes per pad once you have your materials sorted, and a well-made pad can last several years with proper washing. What separates a pad that works from one that leaks or bunches comes down to fabric choices and a few construction details that are easy to get right the first time.
Understanding the Three Layers
Every reusable pad is essentially a sandwich of three functional layers, and picking the right fabric for each one is the single most important step. Skipping a layer or choosing the wrong material is the most common reason homemade pads fail.
- Top layer (against skin): This needs to feel soft and wick moisture away from the surface. Cotton jersey, cotton flannel, or bamboo velour all work well. Cotton flannel is the easiest to sew and the most forgiving for beginners because it does not curl at the edges. Bamboo velour feels luxurious but is slightly trickier to cut cleanly.
- Absorbent core: This is where the pad does its real work. Layers of cotton terry cloth, hemp fleece, or bamboo fleece absorb and hold fluid. Hemp is the most absorbent per unit of thickness, so it makes a thinner pad, but it can feel stiff until it has been washed several times. Cotton terry is widely available and works perfectly well, though you may need an extra layer for heavier flow.
- Bottom layer (facing underwear): This layer prevents leaks. Polyurethane laminate, often sold as PUL, is the standard choice. It is a thin polyester knit bonded to a waterproof membrane. You can also use wool jersey treated with lanolin as a more natural leak barrier, though wool requires more careful washing.
Pre-wash all your fabrics before cutting. Cotton and hemp shrink on the first wash, sometimes by as much as ten percent, and you want the shrinking to happen before your pad is assembled. Two or three hot washes with no fabric softener will get most of the shrinkage out and also strip factory finishes that can repel moisture.
Drafting a Pattern
You do not need to buy a pattern. Grab a disposable pad in the size you normally use and trace its outline onto a piece of cardboard or freezer paper, adding roughly half an inch all the way around for seam allowance. If you want wings, extend two flaps from the narrowest part of the pad, each about an inch and a half wide and long enough to wrap around the gusset of your underwear and overlap by about an inch on the underside.
A typical daytime pad for moderate flow runs about 25 centimeters long and 7 to 8 centimeters wide at its center. For overnight or heavy-flow use, extend the length to 30 or even 35 centimeters and widen the back end by a couple of centimeters. Pantyliners can be as short as 18 centimeters and need only one or two layers of absorbent core. Making several sizes at once is practical since you will already have your fabrics out.
Sewing the Pad Step by Step
Cut one piece of your top-layer fabric, one piece of PUL, and your absorbent core layers using the pattern. The core pieces should be cut slightly smaller than the outer layers, about a quarter inch inward from the seam line, so they do not get caught in the seam and create bulk at the edges.
Stack the absorbent layers in the center of the top-layer fabric, on its wrong side. Baste or pin them in place. Then lay the PUL piece on top, right sides together with the top layer so the waterproof coating faces inward. Pin around the perimeter. Sew around the entire edge with a quarter-inch seam allowance, leaving a gap of about two inches along one straight edge for turning. Clip curves and trim corners to reduce bulk, then turn the whole pad right side out through the gap. Press the edges flat with your fingers or a low iron on the fabric side only, not directly on the PUL. Topstitch around the entire pad about an eighth of an inch from the edge, which closes the turning gap and gives the pad a finished look.
If your machine struggles with the thickness, use a walking foot or a denim needle. A standard universal needle can handle two or three layers of flannel plus PUL, but once you add a couple of terry layers the stack gets substantial. Sewing slowly through the thick spots helps more than forcing the machine at full speed.
Wing Closures and Staying in Place
Wings keep the pad from shifting in your underwear, and how you close them matters more than you might expect. The two main options are snaps and hook-and-loop tape, and each has trade-offs.
Plastic snaps, the kind installed with a simple press-on tool, are the most popular choice. They sit flat, do not catch on other laundry, and last the life of the pad. Size 20 snaps, which are about 12 millimeters across, work well for most pads. Install one on each wing so they overlap and snap together under the gusset. Two snaps per wing give a more adjustable fit for different underwear widths.
Hook-and-loop tape is easier to apply since you just sew it on, but it tends to collect lint over time and can snag delicate underwear in the wash. If you go this route, always close the wings before tossing the pad in the laundry to protect both the tape and other garments. Some people prefer buttons or even simple ties, though these can create a lump you feel when sitting.
Washing and Drying for Maximum Lifespan
The care routine is what determines whether your pads last one year or five. After use, rinse the pad in cold water until the water runs mostly clear. Cold water is key here because hot water sets protein-based stains. You can soak pads in a bucket of cold water with a splash of hydrogen peroxide or salt until laundry day, or you can toss the rinsed pad straight into a wet bag and wash within a day or two.
Machine wash on a warm cycle, not hot, with a regular detergent. Skip the fabric softener entirely. Softeners coat fibers with a waxy layer that repels water, which directly undermines the absorbent core of your pad. Research on cotton textiles confirms that softener treatment significantly reduces water absorbency, creating a trade-off between how soft the fabric feels and how well it absorbs moisture.1Journal of Oleo Science. Improvement of the Water Absorbency of Softener-treated Fabric: Addition of a New Hydrophilic Surface If your pads start to feel like they are repelling fluid rather than absorbing it, a “strip wash” can help. Soak them overnight in very hot water with a tablespoon of washing soda, then wash normally. This dissolves built-up detergent and mineral residue.
Line drying in direct sunlight is ideal for two reasons. First, UV light naturally bleaches stains. Second, the combination of detergent washing and sun drying has been shown to effectively reduce bacterial counts on fabric to acceptable levels.2PubMed. Effect of sun-drying and chemical disinfection on contaminated cleaning cloth You can machine dry on low heat if needed, but high heat can damage PUL over time, causing the waterproof membrane to crack or delaminate. If your pad has a PUL layer, treat it like you would a rain jacket: gentle heat, or no heat at all.
How Long They Last and What They Cost
A survey of 34 reusable pad brands found an average estimated lifespan of about four years, with some brands claiming up to ten years of use.3PLOS ONE. Exploring menstrual products: A systematic review and meta-analysis of reusable menstrual pads for public health internationally How long your homemade pads hold up depends on your fabric choices and your care routine. Cotton flannel tops and terry cores tend to pill and thin out after a couple of years of regular use, while hemp cores stay dense longer. PUL is usually the first component to fail, so some makers create pads with a removable PUL liner that can be swapped out when it starts to leak.
If you are buying fabric specifically for this project, you can expect to spend around $30 to $50 on materials for a full rotation of eight to twelve pads, depending on where you source your fabrics. That is significantly cheaper than buying premade reusable pads, which average about $9 per pad in higher-income countries and about $2 in lower-income ones.3PLOS ONE. Exploring menstrual products: A systematic review and meta-analysis of reusable menstrual pads for public health internationally Most people find they need six to eight pads for a comfortable rotation with washing every two to three days, plus a couple of pantyliners for light days.
Getting the Fit Right for Different Bodies
One advantage of sewing your own is that you can customize dimensions in ways commercial products do not. If you have a heavy flow and always feel like standard pads are too short in the back, add two inches to the rear of your pattern. If you find most pads too wide and they bunch up between your thighs, narrow the center of your pattern by half an inch. The beauty of a homemade pad is that you can tweak and recut after your first trial cycle.
Thong-style pantyliners are another option that rarely appears in commercial reusable lines. Use the same three-layer approach but cut a narrow, elongated shape that matches your thong gusset. A single layer of hemp or bamboo fleece is usually enough for the absorbent core since thong liners are meant for very light days or as backup for a menstrual cup.
For postpartum use, you can make extra-long pads, sometimes called “mama cloth,” that extend well beyond a typical overnight length. These pads benefit from wider wings and an extra absorbent layer. The same construction method applies. Just scale up the pattern and add one more layer of terry or hemp.
Why Fabric Choice Affects More Than Comfort
Beyond how a pad feels, the materials touching your skin have health implications that are worth understanding. Contact dermatitis from disposable pads, while not common, has been documented. A systematic review noted a case of genital dermatitis caused by a biocide used in the adhesive strip of a disposable pad, and a broader review at an Australian dermatology clinic found allergic reactions to this chemical in about 0.7% of patients tested over a decade-long period.4The Ewha Medical Journal. Systematic Review on Sanitary Pads and Female Health That is a small percentage, but if you are someone who has persistent irritation during your period that clears up between cycles, the pad itself could be a factor worth investigating.
A separate concern is chemical exposure from synthetic fibers used in disposable products. One study found that synthetic-fiber sanitary napkins can be a meaningful source of organophosphate ester exposure through the skin, with estimated dermal intake during menstruation comparable to what you would absorb through your diet.5PubMed. Synthetic Fiber Sanitary Napkins: Nonnegligible Exposure Source of Organophosphate Esters in Women The researchers noted that these compounds may interfere with hormone-related enzymes, though the clinical significance of this level of exposure is still being studied. Using cotton, hemp, or bamboo for your pad’s skin-contact layer sidesteps this issue entirely.
In practical terms, a Ugandan cohort study comparing reusable pad users with previous disposable pad users found that self-reported skin irritation dropped from about 73% at baseline to roughly 24% after three months of switching to reusable pads.6PubMed Central. Exploring menstrual products: A systematic review and meta-analysis of reusable menstrual pads for public health internationally That is a single cohort in a specific setting, so the numbers should not be taken as universal, but the direction of the finding lines up with what you would expect when replacing synthetic materials with natural fibers against the skin.
Common Mistakes and How to Avoid Them
A few pitfalls come up repeatedly among first-time pad makers. Knowing them in advance saves you from sewing a batch of pads that do not perform.
- Skipping the PUL layer: Some tutorials suggest using just flannel on both sides. This works only for pantyliners on very light days. For anything heavier, you need a waterproof barrier or you will leak through to your underwear within an hour or two.
- Cutting PUL with pinking shears: PUL does not fray, so pinking shears are unnecessary and they make it harder to sew a clean seam. Regular scissors give you a smoother edge.
- Ironing PUL directly: Heat damages the waterproof laminate. If you need to press a seam flat near PUL, use a pressing cloth between the iron and the fabric, keep the temperature low, and work quickly.
- Making all pads the same size: Your flow varies day to day. Make at least two or three heavier pads for your first couple of days and a few lighter ones for the tail end. A one-size approach means you are either over-padded or under-padded most of the time.
- Using too much absorbent core: More layers are not always better. A pad that is too thick does not conform to your body and is uncomfortable to wear. Two layers of hemp fleece absorb as much as three or four layers of cotton flannel in a fraction of the bulk.
Storing Pads Between Uses and Between Cycles
After washing and drying, fold your pads in thirds with the snap wings wrapping around to hold the fold in place. This makes them compact enough to stack in a drawer or a small basket. If you carry a spare in your bag, a small wet bag or even a zip-lock pouch keeps it clean and discrete.
For used pads when you are away from home, a waterproof wet bag is essential. These small zippered pouches, often made from the same PUL you use in your pads, contain odor and moisture until you get home. You can sew one yourself with a fat quarter of PUL and a zipper, and it takes about fifteen minutes. Having two wet bags in rotation means one is always clean and ready while the other is in the wash.
Between cycles, store your clean pads somewhere with decent air circulation. Sealing them in an airtight container when they are not bone-dry can encourage mildew, and even completely dry natural fibers can develop a musty smell in a closed space over weeks. A fabric drawstring bag or an open basket in a closet works perfectly.
