Celebrate finishing a quilt? Never thought of it before. I suppose it is good for the self-image. Celebrating my own accomplishments! Yeh! This is a good idea. I usually have 3 or 4 I'm working on. So onto the next. And they usually have a deadline, no time to celebrate. But yes, this is a good idea. Give myself a pat on the back.
I think I will hang it in a prominent place in the house. Take a pic and post it here. Take a walk to loosen up the body and do some thinking. Take a break to do something I've neglected to get this done. Then ASAP go onto the next happy project. (As to UFO's, for me quilting is therapy, not a punishment. So if i'm no longer interested or don't like it, I give myself permission to discard it.)
