[pct-l] Tarp construction

[Mike Cunningham]

Steeleye,
 
i use the sheetbend on a 3 mil plastic tarp. Yes, it takes up a lot of space. 
 
I do leave the cord attached to the corners instead of retying.
 
No, there is not much privacy inside.
 
My silnylon tarps have loops on them already so i have not needed to use the knot on them.

Good afternoon, Mike,
Regular tie-out grommets are far-and-away the best, with a pebble-in-the-corner a poor second.  A sheet bend attachment is really poor.
A sheet bend – which has the same bends as a bowline, but for a different application – won’t hold on most of the thin, slick tarp materials.  Even if a sheet bend can be made to hold, considerable material will be required to do so which significantly adds to the sheet wrinkling and sagging tendency.  I would certainly try such a knot under strain conditions rather than assuming it will be successful.

There is a knot called the sheet bend that is used for tying  a large rope or tarp or sail or even a sheet to a smaller rope or cord. It has been  used for centuries and is actually pretty easy to tie. Once you have learned it you need not worry about marbles or rocks or garter belt clips.

Just wondering here if recycling the attachment thingies on ladies 
garter belts for attaching silk hose would be a lighter weight option 
that results in slightly less wrinkling. Probably a little too light 
though since they are expecting silk and not silnylon.
