tearing near the tucked in edges. (pic 2) I solved this by covering the back of the sheets
with clear packing tape. (pics 3 & 4) Masking tape works, in a pinch, and is better by far
than no tape at all. (pics 5 & 6) Another use for duct tape maybe, if that's what you have
on hand. You can cover the entire back of the sheets, or just the edges.
