When you are posting your ad perhaps you could show a sample array of the fabric in one or two boxes, tell what colors arrays you have and tell interested buyers to contact you for any questions they have about the specific colors they're interested in. This way you wouldn't have to post all the colors initally. Once people see the color samples in the posted pics they should have an idea as to the quality and quantity you're offering for the price, per box or lb,you decide to charge.
Good luck down sizing...Andie :lol:
