Like the Sashiko look? Use this line design to quilt along each seamline to add great interest. If all the blocks are matching square sides, a web of interlocking rings is the overall quilting effect. Direct the p2p/line pattern across three contiguous seams, from left to right across the row, then return from right to left designating the fourth seams one after the other. For triangle patches, use Laura's Triangle Arc designs instead. Mix and match with the other secret square arcs!
