Bear, you make a good point. I do not sell, nor do I anticipate selling in the future. If I did, I would charge based on the cost of replacing the fabric today, not the sale price. I also would consider the replacement cost of donated fabrics.
When I gift a quilt it is done with no strings attached. If a friend wants to use a quilt on her dog bed, that is okay with me.
I have a cousin in law who gives home made gifts, then gets upset if they are not displayed or used in the manner she intended. It causes stress in the family. She spends a huge amount of time and money on gift making and is very talented, but she often does not take into consideration the recipients taste, needs, lifestyle etc.
I am planning to make a dear friend a quilt for her 50th next year. She and I have very different tastes. I love bold colour and print, she loves soft colours and pink. I plan to make two quilts and let her choose which one she would like to have. One will be pinks, with a indigo/purple background, the other sherbet colours with white done as hst. I cannot make a quilt without putting a bit of me into it.
