SINGER Fabric Iron-On Patches Assorted Denim Set are the easy solution for both apparel repairs and stylish fabric embellishments. No stitching is needed – simply iron on wherever you want to mend or decorate the material. The four denim patches come in a large 5” x 5” size, perfect for patching holes, mending a ripped knee, or repairing the seat of your favorite jeans. They are also large enough to be stenciled and cut into custom shapes for embellishing clothes, personalizing bags and backpacks, creating appliques, and many other types of decorative projects. In fact, we even included a bonus stencil in the shapes of a star and a heart. The denim patches are made from 100% polyester twill and come in four assorted colors to mix and match: white denim, light grey denim, dark grey denim, and black denim. To use patches, preheat iron for five minutes on “high” or “cotton”. Never use steam or exceed safe ironing temperature. Heat and smooth the fabric to be repaired first by running the iron over the area, then place the patch with the adhesive side down. Press firmly and evenly for 45 seconds, repeating around the edges to ensure that the patch adheres well. After cooling, test the edges to makes sure the patch is sealed all the way around. If needed, or if lifting occurs after washing, repeat the steps above. Hand wash only and air dry.
