Thanks for the tips So if I understood this right, i should sew a patch to the inside of the tarp and then sew the pullout onto the outside using the stitches as a guide? And I don't need to use webbing on the inside to support the pullout? Is 3/4" nylon webbing ok for the pullouts and what is the best way to attach them (loop, flat, etc.)? Also, I used the double boxed x for all of the pullouts on the edges, what method should I use on the wall pullouts? sorry for all the questions, I am just surprised/happy with how they turned out and I don't want to screw up the final steps
