Im looking to make a very long Scarf for my Kaito Cosplay. (see ref) I'm looking at about 20 cm in width and about 2-2.5m in length.
I originally thought That I could make one by attaching lots of rectangle pieces of fabrics together to form one large rectangle. Then folding it in half along its length, sewing along this length then turning it inside out. However the resulting scarf would not stay flat, it kept expanding in the middle into a cylinder.
What is the best way achieve a flat scarf? Also I made the entire cosplay so far out of gabardine, is gabardine be a good fabric for making a scarf?
