This is by no means exciting or ground breaking, but I thought I'd share a little mod I did, and some info on how to roll this tarp up for storage.
This is the 4S cuben tarp with doors.
1.75 zing it spliced into the panel pulls loops. D-rings removed
Roll up and tie off with VELCRO wraps
Roll from end to end and slide into Burrow sized stuff sack, no stuffing involved anywhere!
