905Re: Hammock Camping Near Disaster!
- Mar 24, 2003Regarding the cause/anatomy/etc...
the rip is at the end of the loop velcro. It is perpendicular to the
edge of the fabric and extends about 6 inches into the hammock.
My guess is the cause was the hook velcro of my bug net. I had sewn
hook velcro all the way to the end of the bug net, somewhat
differently than you suggest. It is a little more form fitting to
the opening of the hammock. I'd guess that the hooked together
velcro on the bug net somewhere outside the overhand knot of the
hammock got stuck and as I sat down on the edge of the hammock the
hook velcro, or the sharp edge on that velcro, acted as a knife,
starting a rip.
At this point, I am considering doing something different with the
velcro for the poncho/insulator, so I may just chuck the material for
the hammock and peel off the existing velcro to re-use it. Patching
the material might work, but for the 12 bucks to replace the
material, it seems like too much work to patch and then worry.
