You can sell them here. If you use flat rate shipping boxes , it's much easier. Post photo, and yardage . List the price for the group plus the flat rate shipping. I would put some pre-coordinated bundles together till they fill a flat rate box or flat rate envelope. You could do color groupings or by style. I have been downsizing my stash by listing them here. It was quicker and easier than a garage sale, craigs list , or packing them up to sell at a guild ( many won't allow it if you ar not a member).
