1. Preheat the iron for a minimum of 5 minutes on a medium (silk/wool) setting.
2. Place the patch in position, with the glue backing against the fabric.
3. Press the hot iron against the patch, and hold for no more than 10 seconds as a test. If the patch is fully adhered, you’re done! If the patch requires more time, increase the time in 5 second increments until good adhesion is obtained. We generally find that it takes about 30 seconds to properly melt the glue when you have found the right iron temperature setting.
4. That's it! Your your ready to display your new patch proudly!
- If the glue is not melting, you may need to set the iron to a hotter setting. Repeat the procedure described in (3) – but be careful that you are not scorching the patch or any fabric that the iron may come in contact with.
- It is sometimes easier to melt the glue by turning the article inside out, and ironing from the fabric side. Again, be careful that neither the fabric nor the patch is being scorched by the heat.
- When the patch is securely attached, wait a while for everything to cool and the glue to set before moving
- If you find that the patches come off too easily some time later, probably not enough heat was applied to melt the iron-on glue properly in the first place. When the glue is well melted, the patches usually are very secure.
- Don’t use very hot water for washing, or very hot dryer settings, as these may cause the glue to remelt and the patches to detach. Wash on a cool or warm setting, and dry on a medium or lower setting.
- It may not be possible to iron on the patches to some articles – like plastic backpacks, textured or stretchy fabrics, etc. In that case, the patches can be held in place with a few stitches, or they may be glued….
- If you glue the patches onto very flexible backings, like thin plastic backpacks, it is necessary to roughen up the back of the patch with very coarse sandpaper before applying the glue. This is absolutely essential - because the iron-on glue is very smooth, and roughening the surface is necessary to allow the glue to get a good hold. We have found that Eclectic Products ‘Household Goop’ (available at Lowe’s and Home Depot, etc.) is an excellent glue for this purpose – but only if the back of the patch is well roughened.
- If sandpaper is not available to roughen the iron-on backing, iron the patches onto a scrap piece of cloth as described in the first section above (an old worn out 100% cotton tee-shirt is ideal!). Iron from the cloth side for best results. Carefully cut around the patches, and then glue this new patch backing wherever you need the patches to be. Eclectic Products ‘Household Goop’ (available at Lowe’s and Home Depot, etc.) is, again, a great choice for this purpose.
