I found Mirage's site via a link posted by Just Jeff on WB. On Mirage's site he made a Catenary cut on a hex tarp that he made from Tyvek. I happen to have a partial roll of 10 ft wide Tyvek and I am planning on making both a plain,diamond/sqaure 10'x10' tarp and a Catenary cut.
Is there spefic radius or angle that the sides and the bottom need to be cut at? I am assuming that you need the correct cut to get proper tension when you tie the tarp out. Any help would be appreciated.
