Have you put together a website to sell them on Etsy or another online craft marketplace or maybe featured them on a Pintrest page? I think they are beautiful and would imagine there could be solid demand for them here in the States.
It reminds me of when I lived in Manhattan for a number of years. A friend of mine worked in a store called Sustainable NYC, which featured a number of items made from recycled and re-purposed material. They sold things such as purses made from recycled keyboard keys, and sandals which used recycled tire tread for shoe soles. It was located in Alphabet City and did some brisk business. I admire that you are sticking with your passion.
