These pre printed panels from Olympus Thread Mfg. Co. are called 'hana fukin' with literally means 'flower cloth'. They are printed in grey on light blue coloured narrow width traditional sarashi cloth (an easy to stitch traditional Japanese cotton cloth). Each panel is supplied in one piece with a plain area the same size attached, because they are designed to be stitched through both layers and the edges turned in to make a little cloth, but you can stitch the printed layer separately (as I have done).

'Fujisan to sakura' is Mount Fuji and cherry blossoms, a perfect image for spring, with the sun rising from behind the moutain and swirling clouds.
 
Thread requirements - The (1) on the label indicates that to stitch this all in one colour, just one skein of 20m sashiko thread is needed, but they look great stitched in multicolours too.
 
Sarashi cloth is quite lightweight compared with other sashiko fabrics, but is very easy to stitch, super absorbent and wears well.  It is one of the fabrics traditionally used for kimono underwear!
 
Finished size approx 13in (33cm) square.

Marks wash out. NB - the marks have less contrast than my pre printed sashiko panels.
