FireLine is a durable, thermally-bonded, braided thread made from gel-spun polyethylene (Dyneema) that originated as a fishing line, known for its high tensile strength and resistance to abrasion, stretching, and fraying. Its strength makes it ideal for complex bead weaving techniques and working with beads that have sharp edges, such as crystals, allowing for multiple passes through small holes without damaging the thread or the beadwork.
