This 1.5 by 4 oval patch is made with 3M Scotchlite Reflective Material. The fabric is silver till light hits it then it is bright white.
The pictures are of actual patches. They make a great additions to clothing, caps, totes and backpacks.
I use a 100% polyester canvas with polyester thread. You will have three backing choices:
Heat Seal......This makes the patch iron on up to 30 washings. Will not work with nylon.
Velcro.............Loop part attached to the patch.
Velcro.............Loop part attached to the patch and the hook part that you stitch onto your garment.
