The M1R (which stands for "Make One Right") is a right-leaning increase stitch. It is worked into the horizontal strand of yarn (or "bar") between the first stitch on the left needle and the last stitch on the right.
Use the toggle below to view the M1R performed in the Continental and English styles.

Insert the tip of the left needle from back to front through the horizontal strand (or “bar”) between the next and last stitch to be worked:
This forms a loop on the left needle. With the right needle, knit this strand through the front loop as normal.
The make-one increases can be a bit tricky to get the hang of, because the horizontal bar you pick up is not a true loop like a real stitch. You may need to hold the yarn down in order to get your needle through.
Rather than inserting the left needle from back to front, I find it easier to pick up the horizontal strand from front to back using my right needle and pass it onto the left needle, as demonstrated in the tutorial gifs.
