After bing inspired by the cattail fluff thread, I decided to research a little bit on the uses of milkweed silk, as it is just as common as cattail around my folks place, and it's more than a bit of a nuisance for gardening.
I found out that it's been used extensively! Milkweed silk can be eaten (when the pods are immature) and was used extensively as a medicine by Native Americans. In the forties it was used to stuff pillows, insulate life-jackets and sleeping bags, and had other similar uses.
But what I was really interested in was trying to find out of the silk can somehow be prepared and made into yarn. It's a plentiful enough resource around my upstate NY area, that it'd be a lot more viable than buying a lot of wool or alpaca. I seemed to get close to the information I wanted, milkweed silk can be felted, but I can't seem to refine my search down to spinning. Can anyone give me some advice? Has anyone tried spinning the fine fibers?
