I love to buy kits.....have done so all my quilting life. I like the fact that the fabric is picked out for me as I'm not super good at putting a bunch of colors and fabric patterns together and I really don't want to either run out or end up with a bunch of fabric. I have never run short of any fabric, but if I did, I would definitely contact the seller. I do think if you wait too long to make up the kit, this could be a problem, but..."knock on wood"....so far, so good....
