I've got another one for you -- I was doing the quilting on one of the quilts I'm making for Jan's soldiers and the backing was navy blue. Because there was quite a bit of red on the top, I decided to have blue in the bobbin and red in the needle. Wellllll, when it came time to put in a new bobbin, guess what I did? That's right, I put in RED and proceeded to stitch away. Didn't realize my mistake until THAT bobbin was empty!!! Now I'm ripping out the blue because I decided the red looked better!!!
