It's not as easy as you might believe."
After swabbing and letting dry with alcohol, bond reinforcement patches to the tie out points with GE sil glue. Use a roller, and allow several days to dry. Triangular or half/quarter circle patches for the edges and corners, larger circular ones if needed for points aways from the edges, to spread out the force of the pull. For hemming, bond the patches inside the seam allowance line, and fold and hem the seam allowance over them. Then sew on the tieout tape, stitching at least two inches of tape to the patches, again to distribute force, and reseal. Do not use a bar tack stitch. For wider tape, boxes with Xs inside, or zig-zag figure 8s are good. Worked great for me without clamping. The glue is messy, so use the alcohol and lots of fresh Bounty to keep the job (and your hands!)clean.
