Azumino cotton from Olympus Thread Mfg. Co. is a solid dyed cotton with a subtle texture. It is quite thick and soft - an ideal fabric for sashiko. I used it to make all the sashiko stitch samples for The Ultimate Sashiko Sourcebook, as well as many of the projects, and the sampler quilt opposite the title page, plus projects in my other sashiko books. Azumino cotton looks like the traditional hand woven cotton that was produced at home in Japan, and looks beautiful included in boro inspired projects.
The whole colour range is available as handy 55 x 45cm (21 1/2 x 17 3/4in) precuts, and the most popular colours are available from the bolt by the 1/2m (please contact me to make a special order for any colour from this page that is needed in larger quantities if it is not already listed).
