I have purchased a few kits from crafty and have never run short. One time I messed up a block, was worried I would run short but had plenty to remake the whole block over. Another kit I cut a whole section incorrectly. I contacted them & they replaced the fabric. It was a Jenny Beyer quilt. They ( crafty) are the only place I buy kits from. I do not go through & square up all the fabrics I receive though. I follow the cutting instructions and cut according to the chart.
