Rest and hibernate for the winter. When flat plastic webbing for straps were used, we had to replace belly bands on a weekly basis. Small nylon line lasts much better. Only three bands were replaced last winter. Use screws rather than nails to assemble the frame.
Wind shakes the frame and causes nails to loosen.
Carpet doesn't make good padding because it doesn't adhere to the shrinkwrap. Staple the shrinkwrap padding to the frame and use the shrinkwrap to secure it before shrink wrapping day. Have all of the preparation finished before you start to shrinkwrap. In the fall, calm days may be few and you don't want to waste time padding corners on a calm day. Use a piece of insulation between the shrinkwrap and your boat while you are working.
