These numbers are the greatest!! I’ve ordered these numbers now for several years. My first set of numbers, applied using a heat press (not an iron), still look great. No peeling!! No stitching is required unless you want that stitched-on look. Just make sure to use a zig-zag stitch. Recently ordered B/W/B by mistake. I reached out to Ump Attire about the mistake and they exchanged them with no question!!!

Easy to apply. Does take some time for the glue to fully activate, but once it does, your good to go. Still recommend sewing the patches for permanent hold.
