Seeing as how this was usefull I thought I would attach a photo of the trampoline material and edging. In case it is not what you were expecting.

It is a closer weave than I expected and so may not drain water or spill the wind like a coarser mesh.

As you can see I cut the PVC into 8" wide strips, folded them over the edge of the trampoline once then glued them in place.

All the best
