And look what I've ordered! A 500g bag of waste wool. Perfect for practicing! And there is a decent amount of the brownish colour on the left, might even be able to make something useful! There is some wool that needs carding in there too, so a chance to practice that!
And look what I found when I ordered some fish with the organic box! Wool insulation! I was very tempted to not return the bags, and use the wool instead. I might still approach Abel and Cole to see what happens with the bags at the end of their life ( surely a good wash and the wool would be useable?
