I was directed to a link on craftster about a homemade hackle to make your own roving batts. I thought the idea was absolutly fantastic and set out to buy the supplies needed.
Mark built it for me a bit ago and I took the pound of mill ends ( red, black and a bit of white mohair ) that I received in the shop the swap, and got to work on trying it out.
I just loooove the result, its a very very addicting thing to do.
Heres my hackle, with some of the mill ends on it.
