I just went to a long time quilters estate sale. Her daughters priced all fabric by the pound and that way they did not have to measure any pieces. If you got a lot of smalls or jelly rolls or scraps it all was $4 a pound. It was so much faster and easier. She had an entire room devoted to fabric and there was only room for about six women to stand (not bend over) and reach and grab. We all had to find a place to pile our stuff.
Great items and I walked out with 7 kits, a huge huge bag of fabric, some cross stitch kits which I have finished already, and several books.
But the best idea was to sell by the pound and have two scales. One for the checkout and one for people with questions on what something weighs. Note: A pound of standard cotton fabric is about 5 ounces.
