I just bought one from Craftsy because a) it was a Jenny Beyer and I really want to try one of her designs and b) the sale price brought the cost of the fabric to under $10 a yard, and up here, that is a bargain.
But I have been burned by a kit that had barely enough material and certainly less than the included pattern recommended. The kit was 2 years old and the selling company did not even acknowledge my emails. I have learned to open any kit I buy immediately to make sure that every little thing is there. If not--back it goes!!
