Great information on this thread, as per usual on this board!
It is kind of a funny review for me, as my Mother is a traditional rug hooker and dyes all her wools to make her rugs. And may I add they are so beautiful.
I on the other hand like to dye my fabrics, 100% cotton, for some of my quilts and of course being a child of the 60's....I like to dye my tee shirts!
The processes and chemicals used are sometimes different. And sometimes the prcesses are the same....but never the dyes.
Certainly is an interesting subject on the thread....
