Shaun,
The edge that is flipped over will be much thicker than the
open side. As you roll it up you will find that the flipped
side will gradually bulge. The effect is cumulative.

Secondly, it has been my experience that when you try to
roll such a beast up that you will experience a crinkling
at the flipped edge.

My experience with this method was that it produced more
problems than it solved. The severity of the problem depends
somewhat on the thickness of poly being rolled. It is
much worse with thicker poly.

Hope this helps.
