It’s more a guide than a pattern but nevertheless …….
It’s not only “more a guide” - it IS a guide. It’s not a step-by-step-and-stitch-by-stitch-description - you should be able to implement new stitches within a rib-pattern.
Please note - I used the term “m1” - for “make 1 stitch” - please use “kfb” instead (knit into the front and back of a stitch) - sorry if I confused someone …… :-(
The tweed socks are knitted the same way as described in the pattern but turned inside-out after finishing….
