I understand your question about weight.
This is what I have done:
- I cut the hammock cloth 1 foot shorter
- I sew a rolled over hem, a quarter to a third of an inch wide (This
shortens the hammock about an inch overall, when both ends are considered.)
So I save a foot of hammock fabric length. I think this almost always
will be a weight savings when adding back in the weight of whipping
cord, but not much. For a double bottom hammock it saves two feet of
length. That is where I got my 8 sq ft of savings (my hammocks, as you
know, are 4 feet wide). Since a square yard is 9 sq ft, I figured I
saved 8/9 of the 1.1 oz per sq yard of fabric.
Seen another way, it can save 1/10 of the hammock material weight for my
now 9 foot long material that was 10 feet long before. And I get the
same interior room I had previously.
