I am looking to build up my circular needle stash and was hoping somebody could tell me what length size is a good one to start with. Is it 24", 32" what do you think? I have done only scarves and baby blankets but I want to try other projects. I think I am going to be annal and get all needles sizes in either the 24" or the 32". I figure I will be prepared for whatever project I want to try!
