The Mariner's Compass Block is a a very traditonal block. I have seen the design in tiles, wood and textiles. I decided to update the design, using foundation paper piecing, and added adding the extra element to make the block look like it is exploding. One block makes the 20inch cushion , make more blocks to complete a whole quilt with the design. Fabric choice will change the finished look. Pattern included the master copy that you will need to photocopy to make the block.
