3.25" Chain Maille Round Shield Coasters. The chain maille is made from anodized aluminum and attached to a welded steel ring in the center and a 3 inch ID craft ring on the outer edge. It is stitched to a 5 ounce black veg-tanned leather disc using waxed cotton cord. The leather has been stretched and shaped to create and "umbo" in the center of the coaster. I used traditional round shield designs for these to give them a more realistic look.
