These are white angel wing embroidered iron-on patches (*^_^*) They are also cute when attached to children's t-shirts. The size varies depending on the orientation, but when two are placed side-by-side, they are about 18cm. *Iron-on adhesion is not possible on waterproof or water-repellent materials. 1. Temporary Adhesion: From the front of the material to be attached, place a thin cloth such as a handkerchief or gauze to protect the material and iron it. The trick is to apply weight for about 10 to 20 seconds at a medium heat setting. Be careful not to damage the material with heat and adjust the pressing time. *For polyester and nylon materials, especially thin ones, please be careful. They are weak to heat and may melt. The patch will peel off while it is still hot after ironing, so wait for it to cool down and check that the patch does not peel off. If it peels off, the adhesion is not yet complete, so increase the adhesion temperature and time. 2. Permanent Adhesion: Iron from the back of the material to be attached. Do not forget to use a cloth as a protective layer and press firmly with weight. If the material is thinner than the patch, this step will allow heat to reach the film more directly, making iron-on adhesion more effective. *Iron-on adhesion is not a 100% permanent attachment method, so we recommend attaching it along with sewing m(_ _)m We create them carefully, but as they are handmade, there may be slight distortions or errors.
