Contact the company. I've bought 4 kits from one store. Each kit was short fabric by the time I straightened it out. It was very frustrating. I've also learned with that particular company that if I order a kit I need to make the quilt right away. I will need fabric and if I wait it's gone. Consequently I don't order a lot from them.
OH, and why are they short fabric? I asked. They cut the fabric in stacks and if the piece(s) you get are at the bottom of the stack they are off.
