Repairing velcro on silnylon.

First, use 100% polyester thread (Gutermann’s works great)….

Second,use a realitively fine universal needle ( 11 works well)…finer needle are great but will break frequently.

Third, set your stitch length to 10-12 stitches per inch ( This is a trade off…more stitch is tighter holding on the velcro but bad for the light silnyl)…

Fourth, sew the pad on…Start and end with back stitching… Start on a side in the track and stay in the track for thread down the sides…When crossing over the “ends” recommend triple sewing (Velcro has a way of pulling loose. It usually starts at a corner, where the sewing starts or ends, especially if it was not back stitched at least 3 stitches)….

Finally, seam seal the silnyl side (Silnet Silicone Seam Seal)…

FWIW, I’d replace the velcro with Omni-tape or “No Snag Velro” while you are at it and one side is already off. Omni-tape is easier on you and your gear, works great, also easier to sew (there is not as much thread breakage on the hook side when sewing or in use after)…

Sounds hard, but it is easy…go for it.

These techniques work for JRB and we have sewn hundreds of yards of omni-tape into hundreds of quilts.
