All you knowledgeable spinners and felters, (Helen if you are lurking please answer this question for me.), tomorrow I will give a little workshop for school kids. We are going to make a little Yogurt lid size circle and make a design on or in it for Father's day. I got a lovely alpaca fleece from a friend. We are going to use it for this project. I know why (some) sheep wool will felt. The little barbs on the shaft of the wool fibre, will engage with the fibres next to it, when agitated and washed in hot and cold water. However, Alpaca is not wool, but hair, and does not have these little barbs, but felts well also. Why does alpaca felt so well....
Thank you for any insight you may have on this I would like to have my facts correct when I explain things.
Els
