Don't you hate it when gremlins invade your sewing area and hide things on you???? It happens to me all the time, in fact yesterday I had set aside a fabric to use in a quilt, but when I went to use it, it was gone, just vanished. I guess "Old Timer's Disease" is quickly destroying what little mind I used to have. LOL. Take a break, do something else and it will show up when you lease expect it. Been there, done that, so many times, I just try to laugh at myself.
