18Pcs Embroidered Patch for Clothes, iron on patches/ Sew on patches made of high quality polyester 100% fully embroidered.
For Sewing:
For some backpacks, hats, and heavy fabrics the iron-on method may not work well with heavy materials. You can consider machine or hand sewing them on.
How to iron:
1. You can place the cotton fabric on the patch to secure the cloth before ironing
2. Heat the iron to a moderately high temperature so as not to burn the fabric
3. Place the patch in the desired position and place a pressure cloth (handkerchief or pillowcase) on top to protect the patch.
4. Press the iron down for 15-30 seconds, depending on the fabric. Press the iron from the front for 1-2 minutes, mainly at the edges and corners. Let it stand for 1-2 minutes until the fabric no longer gets hot.
