Hi Jon,
thanks for your reply.
From Schmetz website i see that there are different types of MY1014 (B,D,H,C,SES,SUK,etc.) which do not differ in needle size (Shank-?:1.48 mm,Lenght to eye:38.9mm),but in some characteristics like Stitchtype (Locstitich,Chainstitch),Point style (Medium ball,Light ball,Normal round),and size (from 60 to 100 nm), all of these are suitable for D9 or would you recommend me one particular ?
Then, if I may ask you,the D9 manual lists needles size -2,3,4,5,6,7-, as far as you know, the sizes given by the manual to how many Nm correspond to today's sizes?
