None. I've heard horror stories where someone waited too long to cut out one and the kit didn't contain quite enough fabric and she couldn't find any. I like to pick out my own fabrics anyway. That's one of the funnest parts of quilting. Also, lots of kits have fabrics from the same line and I can go to the quilt shop and look at all the different fabric lines and it's a sure thing that my quilt will look good if I buy fabrics from the same line and colorway. Let me rephrase that - the colors in my quilt will all blend. That doesn't necessarily mean my quilt will look good.
