Are you buying it from a local quilt shop? So that if you run out of fabric, you can get more? I have had bad experiences with kits but have finally figured out it was the store that packaged them that made the mistake. There wasn't a spare inch of any fabric left over and I ran out of 2 fabrics and had to piece scraps to finish the quilt.
A kit that I purchased from a different store was the opposite - I have enough fabric left over to make pillows and small table runner.
So I guess what I'm saying is, if you are getting it from a place with a good reputation and good customer reviews, it might be all right.
