Personally, I love the process of creating figures from beads, which is similar to a mosaic. In this store perler beads you can buy this material to create your figures. The whole idea in beads refers to two hobbies at once. On the one hand it is similar to a plastic 3D pen because it also uses a plastic base and heat treatment for the result. On the other hand the process of creating a figure from beads is very similar to a mosaic by the way. And by the way this mosaic is made of special thermoplastic beads from which very cool figures are created.
