1- You'll need a smooth, dry, and clean surface so make sure the fabric or article of clothing where the patch will be applied is clean, free of creases, and not heat sensitive. Before turning anything on, consider where you want to install your new fix.

2- Find the appropriate setting on your iron for the sort of garment you are ironing. Select a hard, flat pressing surface and set your iron to the appropriate temperature setting without steam.

3- Press down for some seconds to pre-heat the area where you will iron your new patch. By warming the region, you'll make it easier for the patch to melt onto the fabric.

4- The best way to position embroidery patches on fabric is to lay it over the hot area and cover the patch design with a patch pressing sheet or a thin pressing cloth if your fabric is heat-sensitive and contains beads or sequins. Make sure you're working on a dry, flat surface that has enough space.

By following these steps you can easily apply any patch to any clothing.
