These lining inserts are designed for the Jewellery Design Aid Designer Bead Boards. They are made from Vivelle™, which is a paper product made in Germany. It has been cut to size to fit into the outer U channel on the Jewelry Design Aid board, and the middle bead holding area as well. It provides a soft surface for beads and findings. Simply put the inserts in place (non-sticky). They provide a nice color contrast to the boards. If it gets dirty, simply remove and replace with a new one."
