Thanks Franco I am new to this posting so bear with me, I have since found the make your own gear site. However you may be interested to know that by using clear poly and self adhesive patch grommits. I was able to produce a reinforced handy little structure. I limited strech, if not eliminated it bye criss crossing inside the poly with fiberglass reinforced strapping tape. No sewing was involved!
I will submit a post for people who are interested in making one on the other link as time allows. Thanks
