Silk hankies come from cocoons which have been de-gummed, pierced and stretched layer upon layer over a small 25cm square frame. Each cocoon is as sheer as a cobweb.
You can use several layers together for a more textural effect in felt. Silk hankies are also used handspinning or creating silk paper.
They are easily dyed for great effect in felting.
The price is per 500 grams.
