Who knows how much the quilt will bring in when raffled, or has it already been raffled off? I think you did the right thing, you had already committed to your son and his school. That shows your son you are a person of your word and is a lesson to him as well. I think you did the right thing. I just hope the lady doesn't use your pattern and try and sell it as her own. Some people aren't just grateful at all and never like to give credit to who it belongs.
