Years ago I had a short caftan that I really liked. I had purchased it at J C Penney and was able to get another one the next year, but the third year they no longer carried them. I asked a friend who is good at copying patterns if she could make a pattern for it off of the one I had. She did that as well as made me several different ones. I still have one of those that she made for me. She also gave me the pattern, and I proceeded to make them for myself. I decided to lengthen it to a long version and started making them with flannel. I like to have two long, flannel ones so that one can be in the wash. Here's one I just made today to replace one that has a hole in it from my cat's claws. I bought the flannel several years ago.
