ask her if she'll display it for sale on consignment. you know how much you want for it. if she wants ... for example ... 20% of whatever it sells for, set the price as whatever you want + 20%.
if it sells, she'll want more. by doing it on consignment, you can set your own pace of production. if she offers to buy them outright, make sure you get at least what you want for it. have your daughter keep her eye out to see what the shop owner charges for it. if she's putting an outrageous markup and the quilts sell at that price, charge her more for future deliveries. :wink:
