I love crocheting when I feel ambitious enough, and now I feel like making another scarf! I have a pattern for a scarf and it calls for a size K hook. I went to my bag of yarn and got out my hooks and all I have are: I,J,F,G & H. Do I need to go out and buy a new hook or will my J be an OK substitute? I know hooks are cheap, but I don't have much of an opportunity to go to the store and buy a hook. Thanks in advance!
