This will be a list of resources in English regarding sashiko.  

I’m making this list as there is a limited amount of information available in English and there are no cohesive sources for the craft.  This is an attempt to fill that gap.   I have not included books as they are the easiest resource to locate on amazon or other books sellers.

Social Media

Atsushi Futatsuya – website (blog & store), instagram, patreon, youtube
Mr Futatsuya shares not only techniques for sashiko that he learned from his family but also provides important cultural context.  He may be the only Japanese person who is sharing the cultural aspect of sashiko in English.  

Watts Sashiko – website (blog & store), instagram 
An Australian translator who has lived in Japan for several decades and works as a translator.  Her blog highlights her own sashiko work as well as local exhibitions of sashiko.  She also provides (English) reviews for sashiko books published in Japanese.  Unfortunately it appears that she last updated in summer of 2022.  

Xiao Xiao Yarn – website, youtube, instagram
XiaoXiaoYarn provides excellent tutorials narrated in English for sashiko techniques from fabric preparation to drafting to sewing.  She also appears to offer classes in Montreal.  

The Green Wrapper – youtube, instagram
Provides captioned but not narrated tutorials.  Their tutorial for beginning sashiko is a standout as it shows ushin stitching very slowly and close up so its easy to follow the motions.
