I'm interested in starting an online jewlery store. It's something I want to do as a hobby and hopefully will grow into much more. I am specializing in bracelets but being that there are so many and I have never done this before how many of each type of bracelet should I purchase? I'm starting off with 20 styles I just don't want to buy 50 of each and end up with excess if it doesn't do too well. Any advice is greatly appreciated :)
