I sewed it. I thought about the tape but thought the sewing would be stronger. I don't have any close ups but I will take some when I get a chance. The link below is when I first posted about the tarp and tells how I sewed the tie outs. I have changed the tarp to a diamond shape now by adding to the sides. I like only having to use 2 stakes and with my setup rarely have to tie out because the tarp tensioners will reach the stakes.Do you have any close-ups of your tarp's tie-outs and ridgeline? Did you sew or use tape?
