I would take 3 tubes of some kind, maybe pvc piping, cover with neutral fabric, slide the bracelets on (1 of every color, 2 types per pipe = 60 bracelets on each tube) and somehow stagger the tubes, so you can see them all. Or if three tubes is too wide, you could use 6 and have 1 of each color on each tube.
Put your prices on a sign by each type.
I can see it in my head, but sometimes my ideas are hard to get out of my head and into words :(
The tubes would be horizontal. I'm wondering if the knot part would fall to the bottom, though and you wouldn't see them. That might not work.
In addition to the tube idea, I'd put a few out on your table (table raised on risers to countertop level) for people to try on (and hopefully not walk off with). Depending on the crime rate in your neighborhood, you could pin them to your tablecloth. That's what I do.
IMHO, putting them in plastic bags would cheapen them and look like resale. And as I've said in other threads, I have an aversion to jumbles of product in buckets, baskets, bowls, or anywhere!
I like your bracelets. I think you'll sell lots!
