I only sell them in sets of 6 on etsy, otherwise with fees it isnt worth it.
At craft shows I just have a little bin I fill with them and put them at $1.50 each or 6 for $7 so they get a really good deal there
I find that people love to dig through the bins. I have laid them out on a table or put them on bow boards I made for displays, and they do not sell. If I put a bin out I will have a line of ladies just waiting to dig through and find their "treasure"
