Fuse beads

Fuse beads, thermobeads, iron beads, or iron-fusible beads are multicoloured tubular plastic beads that can be arranged into 2D designs on a pegboard, and then fused together by the application of a hot clothes iron through parchment paper to form mosaics. Originally invented as a therapeutic device for the elderly, they were later sold as a children's toy, and have since attracted the interest of hobbyists. Common fuse-bead brands include Hamabeads, Perler Beads, and Nabbi Beads. A similar toy, aqua-dots, are spherical beads that are fused by spraying with water, rather than by the application of heat.
