A simple ski-style hat with a pointy top and optional earflaps.
- Cut pattern as shown with greatest stretch horizontal. As you can see, you could cut on the fold horizontally from N or vertically from G as it suits you. I would recommend G.
- Sew/serge the short edges together (pin them to secure before sewing): CD to ED, FG to HG, and IJ to KJ, and again for their southern cousins.
- Pin PON to QRS and sew/serge, incorporating the southern cousins of BC, EF, HI, and KL into the seam.
- Turn the piece inside out through hole LMNSAB, then arrange seam PONSRQ inside hole LMNSAB so that the short ends BC, EF, HI, and KL are caught too, then sew along, securing the two sets of edges together.
- This protruding seam should be turned towards the inside of the hat, and marks the hat's back. Arrange to have sewn a label into the seam, if you want to make that clear.
If you want the hat a little less silly, make the triangles shorter, and add the removed height into rectangle AMOR.
Curved earflaps with tie-cords to be sewn into the closed hat.
- Cut some rounded V shapes as shown. They should (naturally) be wider and higher than your ear for proper coverage.
- Place one atop the other with half a shoelace between them, and fold the short end on top, so it's caught into the seam while you sew the curved edges of the Vs together (pinning as necessary).
- Turn the earflaps inside out and sew across their straight edges for easier handling later on.
- Pin the earflaps into the hat symmetrically, and make sure they're in the right place to cover your ears, then sew across their tops, through both layers of the hat.
