Bikeaclava! Bikeaclava!

Basic Skills Necessary:

  • Sew a zigzag stitch

Pattern Description:

Bikeaclava is a fast pattern I whipped up to keep the ears of my kid warm while he biked to and from school in the winter cold. From there, it's turning into the family holiday gift.

It's a single layer balaclava in its simplest form; it can get layered and thinned to adjust to bike helmets, big heads, and whatever needs the heads in your life may have. You can reduce this pattern for smaller heads by printing at a reduced percentage - unlike our other parts, our heads are height/weight proportionate.

Will take about 1/4 yard of something a little stretchy for the main cap, and a 8 inch by 24 inch piece of wind resistant material. In the photographs, the head is a stretch Lycra and the sides are a rubbery coated fleece. It will take what you have on hand and keep your head warmer.

Alternate uses: homemade bathing cap, costume bald cap, fearless World War One Flying Ace helmet.

Stay warm, kids!
