I would, and have, mantee it up like I was going to load it on a mule. In a nutshell put the load in the center diagonal, fold bottom up, fold right side over, fold left side over with excess folded under, fold top down with excess folded under, and tie up tight with a mantee rope. stand on end such that the rain will drain from the top down... ... . voile! (excuse the french :-laf )
