Had some spare 1.9 oz waterproof rip-stop (I think its PU as its not greasy like sil but its still stretchy, never seen one quite like it)
cat cuts on all sides with double rolled edges
I only had 16' or fabric to play with so its a bit short at 9' and 8' wide.
Its a French seam with an extra fold in (I think?!) on each side with a full width of rip-stop in the middle with no seam at the apex. pull-out sewn onto this seam on each side
10mm grosgrain tie-outs and pull-outs
14oz with all the cords attached
Not bad for a bit of sewing practice
