How to create a simple pattern and sew a fitted face mask with filter pocket
Making a simple fitted face mask with a filter pocket is an easy sewing project that gives you a comfortable, reusable alternative to single-use masks. With basic measurements, two fabric pieces, and 30–60 minutes of sewing, you can produce a personalized mask that fits well and holds a thin filter. This guide walks you through measuring, cutting, sewing, and finishing for a tidy, wearable result.
Step 1: Measure your face
Take two measurements: from the bridge of your nose to under your chin (about 12–16 cm for many adults) and from the center of one cheek to the center of the other across the nose (about 20–24 cm). Add 1.5 cm seam allowance to all edges and write the final dimensions down. Accurate measurements give a snug, comfortable fit and prevent gaping at the sides.

Step 2: Draft a simple pattern
On paper, draw a curved rectangle equal to half the nose-to-chin measurement by half the cheek-to-cheek measurement, then add 1 cm curve at top and bottom for contour. Cut the paper shape; this will be your center panel pattern. A rounded rectangle creates the fitted 3D shape when two mirror pieces are sewn together.

Step 3: Cut fabric pieces
Place the pattern on two layers of tightly woven cotton (or cotton blend) and one layer of lightweight lining fabric. Cut two outer pieces and one lining piece, plus a narrow strip 4 cm by 60 cm for the filter pocket facing. Use sharp scissors or a rotary cutter for clean edges. Cutting accurately ensures pieces match when sewing and the pocket sits properly.

Step 4: Sew center seams
Pin the outer two pieces right sides together along the long curved center edge and stitch with 0.75 cm seam allowance using a 2.5 mm stitch length. Press the seam open with an iron to reduce bulk. Repeat with the lining pieces if you cut two lining layers; pressing shapes the curve for a better fit against the face.

Step 5: Assemble filter pocket
Fold the 4 cm by 60 cm strip in half lengthwise and press; stitch one long raw edge to the top edge of the lining, right sides together, leaving the other edge open to form the pocket opening. Trim seam allowances and turn the lining so the pocket faces inward. A built-in pocket on the inside keeps filters accessible but contained.

Step 6: Join outer and lining
With right sides together, insert the stitched outer shell into the lining so seams align and the pocket is inside. Pin around the perimeter, leaving a 6–8 cm gap along the bottom for turning. Sew around with 0.75 cm seam allowance, reinforcing at the start and end. This construction hides raw edges and secures the pocket between layers.

Step 7: Turn, topstitch, and add ties
Turn the mask right side out through the gap and push out curves with a blunt tool. Press the edges flat and topstitch 3 mm from the edge all around, closing the gap as you stitch. Attach elastic ties 18–22 cm long or fabric straps at each corner, sewing them into the side seams with a 1 cm stitch length for strength. Topstitching stabilizes shape and secures ties for repeated wear.

- Use tightly woven cotton like quilting cotton for the outer layer and a softer cotton for the lining for comfort and filtration balance.
- If you want a nose seal, stitch a small tunnel at the top and insert a 10 cm flexible nose wire or adapt a metal twist tie covered in fabric.
- Prewash and press fabrics before cutting to allow for shrinkage and cleaner seams when washed later.
- Trim seam allowances to 3–5 mm on curves to reduce bulk and get smoother results after turning.
- Make a paper mock-up first in scrap fabric to test fit; adjust pattern by 0.5–1 cm if you need more coverage or less gap at the sides.
- For easier breathing, use two layers of cotton with a removable thin filter (coffee filter, shop towel) cut slightly smaller than the pocket so it lies flat.
- This home-sewn mask is not medical-grade; do not assume it provides the same protection as certified respirators in high-risk situations.
- Avoid using very thick dense filters that make breathing difficult; if you feel lightheaded or short of breath, stop using that filter and choose a thinner option.
- Wash the mask after each day of use in hot water (60°C) and dry completely before reinserting filters to prevent moisture buildup and contamination.
- Be careful when sewing elastics under tension; secure stitches well and check for wear to avoid ties breaking during use.
