Dritz 1674 Fray Check Liquid Seam Sealant, 0.75-Ounce, 2-Pack (x2)

I’ve heard of “Fray Check” for years but never tried it. I recently started making embroidered patches with my Husqvarna Diamond embroidery & sewing machine and wanted to make sure the patch edges, which have a satin border, don’t fray in the future. Fray Check goes on clear without discoloring the thread nor darkening it, like Super Glue would.
