Wool is the most wonderful material to work with on rugs. I have dyed wool from the factory and I also have overdyed wool which I do myself and get some from the best dealers of wool. I only use the best wool I can find. Dorr, is one of my favorites. It is so soft and I wash all of my wool before dying or cutting it for hooking. My favorite size of the cut is #8. Thank you and keep coming back I will be adding wool very soon.
