No matter how much time you spend on the pattern, the most vital part starts when you need to iron the beads to make them fuse into a seamless pattern. If it is your first time playing around with the pattern, it is advised to begin with a smaller design so that you do not ruin the masterpiece. Usually, the iron is set to medium or high setting. It takes up to half a minute of circular motions to finish the pattern. However, in case you are just a beginner, you can take breaks to adjust the temperature or the design. Also, it is essential that you do not add water to the iron since steam can ruin the Perler beads.
