You could donate to quilting groups. I know a church group I quilt with depends on donations of supplies for their bazaar items. Also, I learned to quilt at a senior center and someone donated material to them. We were able to pick what we needed and it saved a lot of money for new quilters who have to invest in mats and rotary cutters.You could also offer grab bags on the board for a fee if you'd like to make a little money.
