i've been contemplating making double straps for
awhile now. i found out that there is a type of laminated
strap material that is used for horse riding equipment
and as straps for tying down 18-wheeler tarps. it's
going to cost more than 8 bucks, but i got some buckels
from old campy straps and rivet them to this laminated
material which i will cut out by hand using a pattern from
a set of mks double straps.
the problem with the single strap doubler is its no good
unless the single straps are laminated. the lamination is
also what makes straps so expensive. i've yet to find the
same laminated leather material anywhere.
