Simulknit is an accessory for standard-gauge Toyota knitting machines.
Simulknit allows for knitting a fabric with a pattern on one side and a complete backing on the other side. The end result looks like a double sided fabric, but only one side has a pattern.
It has two yarn feeders in one assembly. This assembly looks like a connecting arm between a regular ribber and a regular machine, but with more features. Thus, it will knit when you have your machine and your ribber setup.
