After a LOT of thinking, playing with numbers in my spreadsheet, etc., I e-mailed her a proposal this morning which was $650.74, and included the cost of materials at $246.68, so my labor would have been $404.06. She decided she didn't want to spend that much for a quilt for a guest bedroom, so now we are looking at a much simpler pattern (no applique) and I sent her an estimate for that one and she agreed with it. So we're going to look at fabrics together on Friday. In a way, I'm relieved because I really wasn't looking forward to doing all of that applique again!
