Using these Celtic flower decals is a breeze. First, clean the surface where you want to apply the decal to ensure it's free of dust and dirt. Then, carefully peel the decal from its backing and place it on the desired spot. Smooth it out with a soft cloth to get rid of any air bubbles. When it comes to sizing, measure the area before choosing a size to make sure it fits perfectly. As for colors, you can pick the one that best matches your project's theme. Keep in mind that these decals are made to last, but try to avoid scratching them with sharp objects. For maintenance, a gentle wipe with a damp cloth can keep them looking great. If you have any specific requests, feel free to reach out to us and we'll make a custom decal just for you.
