These increases are used in tons of leethal patterns - often just as "m1", which is knit-wise when the slant doesn't matter; m1L is the standard method for a m1.

Only a few leethal patterns use m1p methods and/or the m1-loop. (Many leethal patterns use kfb/pfb increases, which are not included on this page.)

m1L: make 1 left or just m1: make 1

increase 1 stitch, left slanting, knit-wise

(pictured here with fabric stretched to better show stitches)

pick up strand running between stitches, from front to back

knit into the back

(completed)

m1R: make 1 right

increase 1 stitch, right slanting, knit-wise

(pictured here with fabric stretched to better show stitches)

pick up strand running between stitches, from back to front

knit into the front

m1pR: make 1 purl-wise right or just m1p: make 1 purl-wise

increase 1 stitch, right slanting, purl-wise

when worked on the wrong side of stockinette fabric, shows as a right-slanting m1 increase on the right side

pick up strand running between stitches, from back to front

purl into the front

m1pL: make 1 purl-wise left

increase 1 stitch, left slanting, purl-wise

when worked on the wrong side of stockinette fabric, shows as a left-slanting m1 increase on the right side

pick up strand running between stitches, from front to back

purl into the back

m1-loop: make 1 loop method

increase 1 stitch by twisting a loop onto needle, same as one single cast-on stitch (also known as backwards loop cast-on)

note: this method may leave holes in many leethal patterns; only use the m1-loop as an increase when pattern specifies it
