During the April Weaving Study Group, someone mentioned knitting directly from silk hankies. The question came up: How are silk hankies made and what the difference between that and silk caps?
Silk Hankies and Caps are called Mawata in Japan, meaning expanded cocoon. The hanks are stretched across a square frame while caps are stretched over a piece of curved bamboo. Both are made up of many cocoons stretched over each other. Here are Tips for preparing hanks and caps for spinning
Blogger, Shiborigirl has a wonderful video of reeling the cocoons and making the square hankies.
Knitty.com has a tutorial on spinning hankies.
