I started deciding which things I want to make and writing a list in the colors that I will keep on stock to make more of. I started doing everything in silver and that add about 12 things to my shop. Once I go through every color in each item it will mean that I will have 200-300 items in my shop. That is if I don't expand my line, which I intend to because I get inspired all the time.
I just don't know how many is too many. I don't want to overwhelm buyers with choices but I also want to give buyers a lot of choices.
