When I use textures, I use different textures in the same area I am hooking. This gives much more interesting results than working with a single wool texture.
So when I dye and package textures, I do so in little collections or texture packs. Each pack has four different wools overdyed with the same color dye (1/4 yd total). When hooked together, they give such character and varigation to my rugs. I have a photo here of some textures I just overdyed with McIntosh Million 101.
