Sashiko pre-printed samplers have wash-out stitching lines.  
Do not pre-wash.

100% cotton - Finished size approximately 12 3/4" x 12 3/4".

The design is printed on one half of the sampler.  The other half of the sampler has instructions which will wash out.  You can s
titch through both layers for a little heavier fabric if using it for a quilt square or you can stitch through a single layer and add your own backing.  In Japan, the samplers are stitched through both layers, hemmed and use for tea towels or table decorations.
