The weak points of the Guide Gear tarp (12x12) are that
A - it lacks loops in the middle of the sides so it can be hung in a rectangular set up,
B - lacks sufficient anchors for the panel pull loops located on the three seams across the panel, and panel pulls are stitched only to the panel seam, and
C - the side pull/tie down loops around the exterior seam are only single stitched.

We put 3” square anchor patches under the 3 loops on the center seam and made the same box stitch of the factory loops. 3" and 6" Panel Pull and anchors
