Sashiko samplers are 100% cotton. The design on the samplers are printed with washout stitching lines. There is a plain piece attached to the design half that can be used as a backing or stitch through both layers and add your own backing. The finished size is approximately 13in x 13in. A great take along project, no chart or hoop is needed. No English instructions included but sashiko is an easy over-under running stitch. Just stitch right on top of the printed lines. Sew easy – sew much fun
