100% cotton with vegan adhesive on the back. Can be stitched or ironed on.
How to iron on patches:
Place the patch where you'd like it and cover it with a piece of scrap fabric or a cotton dish towel to protect it. Apply a hot iron over the patch for approx 1 minute.
Flip the garment over and iron the back for another minute.
Allow the garment to cool and check that your patch is secure.
If its not quite stuck repeat the first 2 steps as necessary until your patch is securely attached.
It is not recommended that you iron patches onto man-made fibres as the hot iron can damage your garment or bag. In this instance you should stitch your patches in position.
