Sashiko stitch guides: Seigaiha (waves)
Choose a motif, a grid size and a panel size, then print a true-size guide to transfer to your cloth. Stitches are laid out so that gaps fall at the crossings.
About this tool. Sashiko is a Japanese stitching tradition with its own teachers and many ways of working. This tool only draws line guides. The motif names are ones in common use, and it makes no claims about where a motif comes from. Stitch length and gap are a starting point, so adjust them to your thread, cloth and hand.
