Cochenille offers a set of 3 symbol charts; one for hand knitting, machine knitting and crochet. The Japanese symbol is illustrated and the operation of how to create the stitch is shown. This is helpful for designing your own patterns as it gives you the most common world standard.
This is the digital download PDF version of the three charts:
Hand Knitting
Machine Knitting
Crochet
Each page has a front/back view on the page. It is suggested to print these out on card stock (or adhere regular printouts to a heavier paper) creating a front/back view of each card.
