you can often get a better deal buying new fabric from on-line quilt/fabric shops than what you get from ebay/etsy
shops like 'fabric.com' which gives you free shipping at $35 has many price ranges-and great sales-
connecting threads- free shipping at $50 also good sales-
instead of paying as much shipping as it would cost for 1 or more yards of (used fabric) i would check out what is available new---from reputable shops
