While my girlfriend was working on her quilt we discovered her sewing machine has a little snagging problem. I need to patch a few small holes on the momentum. I still have clean and clear access to the inside of the quilt and plan to apply patches made with momentum on the inside. Would silnet or seam grip work best for this purpose?

Silnet works on silicone impregnated fabrics like sil nylon.  Seam grip works for patches on DWR or PU fabrics.

Just what I was looking for. Thanks!
