Instructions
Purchase good quality sheets with a high thread count. They will support more weight than poor quality sheets. Do not wash the sheets in hot water or use bleach as this will weaken the threads.
Tie simple knots in each sheet at 1-foot intervals.
Tie the corners of sheets together with a sheet bend knot: Curve one corner into a hook shape, with the open end facing left. Take the corner of the other sheet and bring it under the bend of the hook, over the left side, under and over the right side, under itself and over the left side again. Pull the end tight to create a secure knot. Continue tying sheets together until the sheet is as long as needed.
