How To Do A YO In Knitting: Complete Masterclass For Lace Knitters
A yarn over (YO) is an open-work increase in knitting where the working yarn is draped over the right-hand needle, creating a decorative eyelet and an extra stitch without altering the overall stitch count when paired with a decrease. Mastering this fundamental technique is essential for crafting intricate lace patterns, shawls, and lightweight garments with professional tension.
Essential Preparation and Setup for Clean Lace Knitting
Successfully executing a yarn over requires an understanding of how yarn placement alters stitch geometry. Unlike closed increases like the Make One (M1) or Knit Front and Back (KFB), a yarn over creates a distinct hole in the fabric by utilizing the extra length of yarn draped across the needle.
- Essential Gear and Materials: Smooth, non-split yarns such as merino wool, linen, or high-twist cotton blends; needles with sharp points (like ChiaoGoo or Addi Lace) to easily manipulate the yarn loops; and locking stitch markers to track pattern repeats.
- Prerequisite Knowledge: Complete comfort with basic knit and purl stitches, alongside fundamental decrease techniques like K2tog (knit two together) and SSK (slip, slip, knit) to balance stitch counts.
- Production Standards: Maintain consistent yarn tension across the needle shaft; pulling a yarn over too tightly prevents the formation of a clean eyelet, while leaving it too loose results in an irregular, sloppy fabric edge.
Step-by-Step Instructions on How to Do a YO in Knitting
Step 1: Positioning the Working Yarn Between Stitches
Before executing the yarn over, identify where the increase needs to occur within your pattern instructions. Bring the working yarn to the front of your work as if you were about to purl. If the yarn is already at the front due to a preceding purl stitch, you are already in position.
Pro-Tip: Always be mindful of whether your target stitch is a knit or a purl. The direction you wrap the yarn over the needle depends entirely on the identity of the stitches immediately preceding and following the eyelet.
Step 2: Draping the Yarn Over the Right-Hand Needle
To form the loop, take the working yarn and bring it over the top of the right-hand needle to the back. If you are working a yarn over between two knit stitches, you will wrap the yarn completely around the right needle. If moving from a knit to a purl, the motion naturally occurs as you shift the yarn to the front of the needle between the two stitches.
Warning: Never wrap the yarn counter to the natural mounting of your stitches unless explicitly specified by an advanced lace chart, as unintended wraps will introduce twisted stitches and distort the size of the resulting eyelet.
Step 3: Working the Subsequent Stitch Securely
With the yarn now draped over the right-hand needle to create your new loop, insert your right needle into the next stitch on the left needle according to your pattern instructions. Knit or purl that next stitch normally, ensuring the newly formed yarn over does not slip off the tip of the needle.
Step 4: Managing the Yarn Over on the Following Row
When you encounter the yarn over on your return row or subsequent round, treat it as a standard working loop unless the pattern instructs otherwise. Knit or purl into the front of the loop to create a stable, open eyelet that sits neatly within the surrounding fabric matrix.

Yarn Over Variations and Structural Specifications
| Yarn Over Type | Execution Method | Primary Use Case | Sizing & Tension Impact |
|---|---|---|---|
| Knit-to-Knit YO | Bring yarn to front, over needle to back, then knit next stitch. | Standard lace designs and basic eyelet rows. | Creates a balanced, centered eyelet with moderate loop size. |
| Knit-to-Purl YO | Bring yarn around the right needle to the front, then purl. | Transitional rows in textured lace and ribbing. | Minimizes loop expansion between contrasting stitch types. |
| Double Yarn Over (YO, YO) | Wrap the yarn twice around the right needle between stitches. | Dramatic, large decorative eyelets in lightweight shawls. | Requires dropping one wrap on the return row to prevent excess yarn buildup. |
| Backward Loop YO | Twist the yarn onto the needle manually to form a closed loop. | Cast-on methods and edge-stitching modifications. | Tighter tension, restricts the size of the opening. |
Troubleshooting Common Yarn Over Errors and Field Fixes
- Unintentional Stitch Count Increases:
- Root Cause: Forgetting to pair the yarn over with a corresponding decrease (such as K2tog or SSK), or accidentally adding an extra wrap when moving between knit and purl stitches.
- Actionable Fix: Count your stitches at the end of every repeat. If your count is too high, locate the stray loop, drop it off the needle, and let it ladder down to the error point before weaving the excess yarn into the adjacent stitches.
- Drawn-In or Puckered Lace Fabric:
- Root Cause: Pulling the stitches immediately following a yarn over too tightly, which starves the loop of necessary slack.
- Actionable Fix: Intentionally relax your grip on the working yarn for the two stitches immediately following a yarn over, allowing the eyelet to bloom to its proper gauge.
- Unwanted Twisted Eyelets:
- Root Cause: Working into the back loop of the yarn over on the subsequent row, which twists the base of the stitch and closes the eyelet prematurely.
- Actionable Fix: Always work into the front leg of the yarn over loop unless the pattern chart explicitly dictates a twisted stitch variation.
Frequently Asked Questions
What is the difference between a yarn over and a standard increase?
A standard increase like M1 or KFB creates a new stitch by working into the strand between stitches or working a single stitch twice, resulting in a closed, dense fabric. A yarn over deliberately introduces an open eyelet hole into the fabric by draping the yarn over the needle without anchoring it to a lower row.
Why does my knitting pattern tell me to do a yarn over without a decrease?
When a yarn over is worked without a simultaneous decrease, it functions purely as an increase to expand the total stitch count of your piece, commonly used in top-down shawl shaping. When paired with a decrease, it maintains a neutral stitch count while adding decorative lace details.
How do I handle a double yarn over on the next row?
On the return row, treat the double wrap as two distinct stitches by working the first wrap normally (often by knitting it) and purling or dropping the second wrap according to the specific design requirements of your lace pattern.
Can I do a yarn over when working with bulky or novelty yarns?
Yes, but you must be careful with fuzzy or textured novelty yarns like mohair or boucle, which can obscure the eyelets. Use slightly larger needles to ensure the yarn over holes remain open and clearly defined.
How do I fix a dropped yarn over several rows down?
Use a crochet hook that matches your needle size to catch the dropped yarn over loop and ladder it back up through the horizontal strands of the intervening rows, anchoring it securely into the top row.
