My goal was to duplicate the lay of a Warbonnet hammock, so all I do is gather the material up using a small cord in the end channel. It just bunches up evenly as you pull. End result is a very comfortable lay but the sides are a little floppy. Sometimes I add a footbox triangle to one side to keep my quilts from falling out. The footbox triangle shortens the side of the hammock but does not affect the lay.
