I've never had to but that's not to say it will never happen to me. I'm a good one for getting close to the end of a project and then deciding it needs something more. Then I start digging in my stash to see if I have something else I can add to give it that final zing. Some times I have what I need and sometimes I don't but if I don't, it doesn't take me long to go get something so I can get it finished and off my ever growing list. I'm so happy you can now put the finishing touches on your quilt. Be sure to post a picture of it when you get it done.
