What M1R Means and When You Use It

M1R stands for "make one right" and is a method for increasing stitches by one on your needle. Unlike yarn-over increases, which create a visible hole, M1R produces a nearly invisible increase that leans to the right. You use it when a pattern calls for a right-leaning increase, often paired with M1L (make one left) to create balanced shaping on either side of a garment.

M1R appears in patterns for fitted sweaters, shawls, and anywhere the designer wants the increase to blend into the fabric rather than stand out as a decorative element. The stitch sits between two existing stitches on your needle, so you are not working into a stitch that is already there — you are creating a new one from the strand of yarn that runs between them.

Key Takeaways

  • M1R creates a new stitch from the horizontal strand between two stitches by lifting it onto your needle and knitting through the back loop.
  • The stitch leans to the right because you work into the back of the lifted strand, which twists it in that direction.
  • M1R pairs with M1L (make one left) in patterns that need balanced increases on both sides of a center line.
  • The increase happens between two existing stitches, so you do not skip or drop any stitches in the process.

How to Execute M1R in Five Steps

Position your working yarn so it runs from your right needle to your left needle. Insert your left needle from front to back under the horizontal strand that sits between the stitch you just worked and the next stitch on your left needle. This strand is the one that connects the two stitches together.

Once the strand is on your left needle, insert your right needle through the back loop of that lifted strand (not the front). This is the critical step that creates the right lean. Knit through the back loop as you would a normal stitch, then slip the new stitch onto your right needle. You now have one more stitch than you started with, and the increase is complete.

The whole motion takes practice to feel natural. Your left needle tip will be pointing to the left when you insert it under the strand, and you will feel the yarn shift slightly as you lift it. Work slowly the first few times until the motion becomes automatic.

Why You Knit Through the Back Loop

Knitting through the back loop of the lifted strand is what makes M1R lean right instead of left. When you insert your needle through the back of the loop, you twist the strand, and that twist creates the directional lean. If you knitted through the front loop instead, the increase would lean left — which is the definition of M1L.

The lean is subtle but visible when you look at the finished fabric. In patterns that use M1R on the right side of a garment and M1L on the left side, the two increases mirror each other and create a balanced, professional appearance. Skipping this detail or mixing up the direction will make the shaping look uneven.

Common Mistakes and How to Avoid Them

The most frequent error is inserting the needle through the front of the lifted strand instead of the back. This happens because knitting through the front loop feels more natural — it is what you do for every other stitch. Slow down and deliberately aim for the back loop, especially when you are learning. Some knitters find it helpful to say "back loop" out loud as they work.

A second mistake is lifting the wrong strand. The strand you want is the one closest to your working yarn, running horizontally between the stitch you just completed and the next stitch waiting on your left needle. If you lift the strand that is one stitch over, your increase will be in the wrong place and the pattern will not line up.

Tension can also cause problems. If you pull too hard after the increase, the new stitch will look loose or uneven compared to the stitches around it. Work the stitch with the same tension you use for the rest of your knitting, and the increase will blend in.

M1R in Different Stitch Patterns

In stockinette stitch (knit on the right side, purl on the wrong side), M1R is nearly invisible. The increase sits between two knit stitches and looks like part of the fabric. In ribbed patterns, the increase may fall between a knit and a purl stitch, which can make it slightly more visible depending on where the pattern places it.

In textured stitches like garter stitch or seed stitch, the increase is even less noticeable because the texture already breaks up the visual line. Some designers use M1R in lace patterns, where it sits alongside yarn-over decreases to create a balanced motif. In those cases, the increase is intentionally visible as part of the stitch pattern design.

M1R Versus Other Increase Methods

Yarn-over increases (YO) create a deliberate hole in the fabric and are used for lace and decorative shaping. Knit-front-and-back increases (KFB) work into the same stitch twice and create a small bump. M1R, by contrast, lifts an existing strand and creates a smooth, nearly invisible increase that does not alter the stitch count in the way KFB does.

Bar increases (knit into the stitch below) are another option, but they create a visible horizontal line. M1R is the choice when you want the increase to disappear into the fabric. Patterns will specify which method to use, and using the wrong one will change how the finished piece looks and fits.

Practice Drills to Build Confidence

Cast on 20 stitches and knit a few rows in stockinette stitch. On the next row, place markers every four stitches. Work M1R between each pair of markers across the row. You will end with 25 stitches. Knit several more rows and look at how the increases sit in the fabric. They should be nearly invisible.

Once that feels solid, try alternating M1R and M1L on the same row. Cast on 20 stitches, knit a few rows, then on the next row work M1R after the first stitch, knit to the center, work M1L, knit to the last stitch, work M1R. This mimics how increases appear in actual garment patterns and helps you see how the two methods balance each other.

Frequently Asked Questions

What is the difference between M1R and M1L?

M1R leans to the right because you knit through the back loop of the lifted strand. M1L leans to the left because you knit through the front loop. Patterns use both together to create balanced shaping, with M1R on one side of a center line and M1L on the other.

Can I use M1R if my pattern does not specify which increase to use?

If the pattern just says "increase one stitch" without specifying the method, M1R is a safe choice for most situations. It is invisible and works in nearly any stitch pattern. However, if the pattern shows a schematic or photo of the finished garment, look at the shaping to see if the increases are meant to be decorative or hidden.

What do I do if I lift the wrong strand?

If you realize mid-stitch that you lifted the wrong strand, drop the stitch from your needle and try again. It is much easier to fix the mistake before you complete the stitch than to rip back rows later. If you do not notice until several rows later, you can either live with it or rip back to that row and redo the increase.

Does M1R work the same way on purl rows?

Yes, the mechanics are identical on purl rows. Lift the strand between two stitches onto your left needle, insert your right needle through the back loop, and purl the stitch. The back-loop insertion still creates the right lean, even though you are purling instead of knitting.

Why does my M1R look loose compared to the stitches next to it?

Tension is usually the culprit. The new stitch is created from a strand that was not previously worked, so it can feel looser than the stitches on either side. Work the stitch with the same tension you use everywhere else, and block the finished piece to even out any minor differences.
