Trinket Trader Question!

So I'm going to my first ren faire in Feb [AZ] and I decided to make some bracelets to trade. How many should I make??? I have 12 options but I'm stuck between making 5 of each [60] or 10 of each [120]. I have no idea how many is too much and I've lowkey hyperfixated on it all day. None of my friends could answer me so I hope you all can haha.
