Light blue frog iron-on patches, set of 4 Size: Approx. 4cm (height) x 5cm (width) Perfect for adding a little accent to your child's belongings! *Iron-on adhesion is not possible on waterproof or water-repellent materials. 1. Temporary Adhesion: Place the patch on the front side of the material you want to attach it to. Use a thin cloth, such as a handkerchief or gauze, as a protective layer to prevent damage to the material. Iron for 10 to 20 seconds at a medium heat setting, applying weight. Be careful not to damage the material with heat and adjust the pressing time accordingly. *Please be especially careful with thin polyester and nylon materials, as they can melt due to heat sensitivity. After ironing, the patch may peel off while still hot. Wait for it to cool down and check that the patch is securely attached. If it peels off, the adhesion is incomplete. Increase the ironing temperature and time. 2. Permanent Adhesion: Iron from the back side of the material. Remember to use a protective cloth and apply firm pressure to ensure good adhesion. If the material is thinner than the patch, this step will allow heat to reach the film more directly, resulting in more effective iron-on adhesion. *Iron-on adhesion is not a 100% permanent attachment method. We recommend sewing the patch on in addition to ironing for a more secure attachment. m(_ _)m
