Ha!!
I may have discovered a new one the other day - pinning a quilt top over another quilt top on the design wall, because I was in a hurry and didn't want to take the first one down just to finish up a baby quilt. I'm sure that's a bad idea for a few reasons, but it worked! Baby quilt got finished just in the nick of time and has been successfully gifted, and the other quilt top is just fine.
