Our range of iron-on patches are embroidered designs that have a protective backing on the back which is covered in a heat-activated glue. We recommend not trying to remove this backing even if you choose to sew the patch on instead as it helps to hold the embroidery stitches in the correct position.
Make sure that the fabric you are trying to adhere the iron-on patch to is suitable for use with an iron. You may wish to test a fabric offcut or a spot that is out of sight first. A pressing cloth (or piece of cotton) can be used over the patch and fabric to help protect the surface of the fabric and patch.
You might find it helpful to pin the patch in place prior to fixing to be sure you are happy with the location especially on clothing where you may want to try it on first. A tape measure can be useful to help you centering a patch too.
Make sure pins are removed prior to fixing in place and that the fabric is clean and flat. If you are using the patch to cover a hole in the fabric you may want to use greaseproof paper under the fabric to stop the patch from sticking to the fabric on your ironing board or other fabric layers underneath. The iron needs to be on the hottest setting suitable for the type of fabric you are adding the patch to with no steam. Be careful not to move the iron around as this can shift the position of the patch. It is better to hold the iron still. Hold for approximately 15 seconds, then flip the fabric and repeat on the reverse. Let it cool completely before checking if it has fully adhered (lower heat settings may require longer, but it is better to use shorter times repeatedly than risk scorching the fabric by holding the iron in the same spot for long periods).
For fabric items that will be frequently washed, you may want to sew around the edge of the patch to the fabric underneath to prolong the life of the patch by preventing the edges from lifting or curling in the washing machine. Gentle hand washing is another way to help protect the patch and help it last longer.
