WARNING: Do not attempt to iron patches onto satin, nylon, rayon, or any tri-acetate fabrics, or any fabrics that will fail at 400 degrees. Do not iron onto leather.
Follow these instructions and your iron-on patches are guaranteed to stick firmly.
- Find a nice, hard flat surface to iron on.
- Set your iron to the hottest setting, but don't put any water into the iron.
- While the iron is heating up, find an old t-shirt or thin pillowcase that you wouldn't mind having a burn mark on it. This will be your pressing cloth and always be between the patch and the iron.
- Line up the patch where you want it, cover it with the pressing cloth, drop the iron on it, and press down hard for 45-60 seconds.
- Don't move the iron back-and-forth like you are pressing a shirt, just press straight down and let the patch absorb all the heat.
- You will be melting a thin layer of adhesive on the back of the patch into a hot tacky glue. Some thinner patches will take less time than thicker patches.
- Wrap your finger in a towel and as soon as the iron comes off, use your covered finger (the patch will be scalding hot) to press the patch into the item it is being ironed onto.
- Allow to fully cool before testing to see how well the patch stuck. If you need to touch up a corner or you think it should attach more firmly, repeat the above steps with an additional 10-15 seconds added to the pressing time.
- We have sold hundreds of thousands of patches over the years, and if ironed on correctly, these will all stick extremely firmly.
Ironing onto leather.
- Many patch sellers will lie and tell you that you can iron patches onto leather. Truth is, you can't
- Following the instructions above, the heat from the iron will discolor the leather or even dry it out so that it cracks.
- Some high-end leathers can take the heat -- but these types of leathers will not take the glue.
- For best results with leather, we always recommend sewing the patches on. They will last a lifetime.
- If you are sewing by hand, we recommend a 1/8th-inch blanket stitch
- If you are sewing by machine, never use a straight stitch (this will cut the patch). We recommend zig-zag setting set to 15-stitches-per-inch
- If you need someone to sew it on for you, a local tailor is often your best bet. But for heavy leather jackets, also try your local shoe repair shop. They have heavy duty sewing machines built to sew through leather, will do it cheap, and are usually happy for the work.
