This is EDJI 2.0 which means that it now fits most CSM's, including Erlbachers, Gearharts, Legares, Chambords, Creelmans and Autoknitters.  EDJI 1.0 was born at the Erlbacher homecoming in 2023 when Jim came up with the idea for a CSM needle cover.   Fortunately, Ed from Joyce Knits and Sews was on hand with his 3D printing know-how.  Together Jim and Ed invented the EDJI, the gadget that every CSM owner needs to protect their needles and knitting.
