I bought a large bag of washed but un-dyed wool with the idea of dyeing. I tried a small amount and it took the dye very well and rightly or wrongly I was careful to not heat the dye bath up too much. I kept this at below 140 deg farenheit (60 deg C). However on drying out it had matted like felt and took an age to unpick it almost strand by strand, so it was easily useable for dubbing. Does anyone else have experience of this and know what to do about it? I wondered about getting a couple of carding brushes or dog brushes, would this work?
