Modified Gather Bind Off: Cut the working yarn coming from the hat, leaving 16- 20” for the gathering process. Use yarn tail to hold the stitches that are removed. *Skip the first two pegs, and remove the stitches from the next two pegs and place on yarn tail. Repeat from * to the end of round. Next, go around the loom again removing the remaining stitches. Cinch the top closed. Weave ends in.
Important: On cast on edge (brim of hat), tighten the initial stitches to take out the slack, so that the edge is straight and tight. Work to end of row. Knot and cut excess yarn. This creates the nice close fit around the face.
