Hi Tammy,
Normally retailers will double the wholesale cost to determine retail price. This is called keystoning. Jeweler's will triple the price; grocers will mark up food way less than double, but for leather masks they should double it.
Consignment should mark it up less than that, and did when I got started years ago. It used to be 67% went to the craftsman, then it went to 60%. When it went to 50% I stopped consigning. Retailers have nothing invested in consignment goods except for wall space, so they would rather sell goods they've bought outright.
I recently went to a local craft/gift shop to see if they wanted to carry my masks (in the past they've bought other craft items from me). The owner said they no longer buy outright--just do consignment. She also said she was expanding her website to sell online, and she would include my masks.
Well heck, I can do that myself and get 100%! I have recently opened a shop on Etsy, and have had success selling there. I recommend it.
