Having done custom quilts before I became disable, beware of the many pitfalls that will come your way. You have to be able to present her with an accurate design of what the quilt will look like. Most non quilter's do NOT understand the cost of labor when they see the quilt imports from China being sold in the store and on the TV shopping channels. I always passed on any savings that I accumulated for my customer such as thread. These are still tough economical times. It is NOT as much fun working on someone else quilt than it is working on your own. Good Luck. Looking forward to seeing a photo of the quilt.
