I bought both the small and the standard size binding tools (the small one by mistake - cheaper to keep than post it back to the US from Australia). Even at this early stage in my learning I think they'll end up in a cupboard unused. I have come across one or two videos which just make a lot of sense without the complications.
Actually I'm already amassing a small collection of bits and pieces that I don't think I'll use. Guess it's part of the learning process.
