For starters, you will need access to an industrial duty sewing machine. A typical sewing machine won't be strong enough to do the sewing necessary.

I am currently working on restitching my weathered 6.0 trampoline and fortunately have a friend who just bought an industrial sewing machine (he claims it can actually sew plywood together). I'm looking for ideas on trampline storage - anyone have any? (I think I'll start another thread on the matter).
