Beth & her husband are DIYing again for spinners

She and her dad (?) already made a Louet-type spinning wheel, and now she & her husband have made wool combs and will tell you how.
Personally, I got some dog undercoat rakes to do this with. One of them is too short and the other is really too short. With the longer rake and an afro comb/pick thing I can do the combing, sortof. Didn’t enjoy it too much, though. I’ll try again sometime…
