Silk Throwster's waste is one of my favourite fibres. It's soft and fluffy and fibrey and like nearly all silk products, really shiny. It can be very expensive too, and you don't get much for your money. 'Raw' silk throwster's waste, however, is very inexpensive. Many people are put off buying it because it has to be de-gummed and dyed, two things which can seem daunting, especially if you don't have much room.
It really isn't very difficult at all, and you don't need any fancy equipment or hard to find products.
If you'd like to know how to go from this:
Please visit the Felting and Fiber Studio site, for the degumming tutorial and the tutorial for direct dyeing.
Both tutorials have lots of photos and easy to use tables for degumming or dyeing small amounts of fibre.
The direct dyeing method can be used for both silk and wool/other animal fibres and is particularly useful for those of us who dye small amounts, or use small amounts of many colours.
