Step 1: First Part of Mask

-HDC in first ch on first loop hdc in 9ch sts, dc in next ch, ch1, dc in next ch. hdc in next 3 chs, 2hdc in next 2 chs, hdc to end.

-work your way over to the other loop, and do the same starting at the top hdc in 9 ch sts, dc in next ch, ch1, dc in next ch. hdc in next 3 chs, 2hdc in next 2 chs, hdc to end.

Make two of these.

Step 2: Pipe Cleaner

Form and trim your pipe cleaners into the shape of the mask.

Step 3: Sew Together

Sew together the two mask shells with the pipe cleaner sandwiched inside. Trim and weave in all ends.

Step 4: Mask Straps

Step 5: Sew Straps

fold your mask in half and mark on each side where you want to place your straps, so that you can sew the straps evenly on both sides.
