Did you give her a coupon? I have to play devils advicate here. I have 5 children and there are certain school things I hate paying for. Examples: science fair projects, memory sticks for computer classes. Each one of those costs me $10-20 per kid. I have 3 of them very close in age 2 are twins so when it rains it pours! I can undstand why a non quilting parent has issues with spending money on fabric. You should go about it a different route and explain it in a way where the parents focus is off the cost and on her childs participation in the project. Maybe that will help and I love to hear more kids are being taught to quilt!!
