I have separate notebooks, and pattern storage boxes! They are sorted by category!
BUT, here lately I have decided that I will NEVER live long enough to use all the patterns and books that I have, and I am making photo copies of the patterns I really want to do, and then selling them off!
Books are next...but I am not copying any patterns out of them,..they are just going in to EQ if I REALLY< REALLY like them....
