We always recommend that all patches should be sewn in a few locations to ensure your patches remain secure through use.
To activate the iron on backing on your iron on patch, follow the directions as outlined below:
Heat iron to 400 degrees (The “cotton” setting). Do Not use steam.
It is also recommended to pre heat the fabric where the patch is to be placed.
Place iron on backing side of patch onto the item. Cover with a cotton cloth and press firmly for 15-20 seconds. With the gold finish shiny fabrics we recommend a slightly lower temperature and a thicker cloth.
Then turn the item if possible inside out and iron back side of patch for a further 20-25 seconds.
If not quite fully secure repeat process.
You could also try fabric glue to attach your item, especially it item is unable to be ironed.
