Contact the company. I cut a strip wrong from a kit and couldn't finish the quilt. I don't know why I waited but it was a couple years later and I was going to the quilt show in Chicago (where I had bought the kit) and took the strip with me. The vendor was there again so I stopped and told her I needed a quarter of a yard of this material and showed her the strip. She asked if it was from one of their kits and when I said yes she told any time that happens, mail the strip and they will sent a matching replacement. It is cheaper than putting extra fabric in each kit. Granted the quilt had 25 or 30 fabrics so I understood that. Got the piece I needed the following week in the mail.
