A couple of months ago I lost a quilt top, and like you all say, I looked EVERYWHERE.... many times. It was driving me crazy so I decided I just had to put it out of my mind and someday it would show up.
Wellllll....as it turned out I was getting some flannel out of a box to make a baby quilt and what do you suppose was RIGHT ON TOP of all the flannel???.........my quilt, which was folded with the batting to the outside so it looked just like more white flannel!!!
These sorts of things can drive you crazy if you let them!!!
