It has though and I want to expand some of the things I offer but haven't got the money to do so. I don't sell enough to try. So this is possibly an option and I wouldn't mind opinions on it.
For all the colors available in the 16 and 18 gauge aluminum rings I use and to move into using Niobium (which is a strong, corrosion resistant and hypo-allergenic metal) as well as getting specially prepared
I would set the goal a bit higher probably though, to cover all that plus the shipping costs and the cost for listings on etsy as well as dealing with any possibility that the tools won't be prepared right.
Ardruna: Yep, basically. Materials and shipping and tools because mine aren't smoothed. They don't have teeth but they scrape all the same and it drives me nuts.
