This is a tough one. I have no problem doing charity quilts and giving them away, but they are usually made from simple designs and "extra" fabric.
The hard ones are the original designs with "tons" of time involved...but if it was made for someone in mind, I can still give it.
However, I participated in an opportunity quilt that was heavily appliqued and all hand pieced and hand quilted. When it was time to give it up, one of our participants had passed away. The person who won the quilt paid a dollar for the chance. She only bought one ticket. So, I tried to buy it back from her so that we could keep our friend close.....
She refused at any price...
that was the hardest one.
