Please help! I am knitting slippers and I am confused about a step.
The instructions are K3 M1 K1 (place a marker on last st) M1 K5 M1 K1 (place a marker on last st) M1 K3
What I am confused about is the M1 step. I know that M1 means to make one, but I searched youtube videos on how to do it and it looks like there it an M1r and M1l. I don't know which one to use! Do I use just one? Do I use both and if I do which M1 is right and which M1 is left?
