It is VERY hard to make a quilt for a customer especially if you haven't done it before. Custom work is the hardest to do. You must make sure she OKs the fabric and the pattern. Try to save your customer money, checkout where you can get the fabric on sale. Pick up the batting and thread at JAF with some 50% coupon. Watch for sales. Hope she is not expecting this for Christmas. You do NOT want your landlord being upset at the estimated cost of the quilt. Keep the pattern simple. I always love the BQ2 pattern. You can piece the top in just a couple of days. Good Luck.
