M1R vs M1L
M1R and M1L are mirrored make-one increases used for balanced shaping.
What it is
M1R leans to the right and M1L leans to the left. Patterns use them as a pair around raglan lines, side shaping and other symmetrical increase points.
How Ruke patterns use it
Ruke pattern instructions often place M1R and M1L around markers. The difference matters because swapping them changes the visual direction of the shaping line and can make a paired construction look uneven.
Examples
In Yoga Summer Sweater, M1R and M1L are worked around raglan stitches and markers in the yoke.
Use this comparison page when a knitter sees both abbreviations in one instruction line and needs to decide which side leans where.
When to use it
Use it when a pattern uses paired make-one increases and the knitter needs to understand which direction each increase leans.
What to check
Check increase placement around markers and confirm that M1R and M1L are not swapped on mirrored sides.
