What Ask Knitting Does and When to Use It

Ask knitting — written as "ask" or sometimes "ssk" (slip, slip, knit) — is a decrease stitch that removes one stitch from your needle and leans to the left. You use it when a pattern tells you to decrease, usually to shape the edges of a garment, create a decorative line, or taper a sleeve. Unlike knit two together (k2tog), which leans right, ask creates a mirror-image decrease that balances shaping on both sides of your work.

The stitch appears in nearly every fitted garment pattern — cardigans, sweaters, hats with shaping, and shawls all use ask to control the width. Learning it now means you will not hit a wall when you move beyond basic scarves and dishcloths. The motion is straightforward once you see it done, and it takes about the same time as any other decrease.

Key Takeaways

  • Ask is a left-leaning decrease made by slipping two stitches one at a time, then knitting them together through the back loop.
  • The stitch removes one stitch from your needle and is used to shape garments and create balanced decreases on both sides of a piece.
  • Ask leans left; knit two together (k2tog) leans right — patterns often pair them on opposite sides for symmetrical shaping.
  • Common mistakes include knitting the slipped stitches instead of slipping them, or forgetting to go through the back loop on the final knit.
  • Practice the motion on a swatch before working it into a pattern so the tension stays even and the decreases look neat.

The Step-by-Step Motion

Hold your working yarn in your right hand and your needle with stitches in your left. Bring your right needle toward you, from left to right, and slip the first stitch from the left needle to the right needle without knitting it. Do the same for the second stitch — slip it the same way. Both stitches now sit on your right needle in a loose, unworked state.

Insert your left needle through both slipped stitches from left to right, going in from the front. This is the key moment: you are going through the back loop of both stitches at once. Wrap your working yarn around your right needle and pull it through both loops in one motion, as if you were knitting. You now have one stitch on your right needle, and you have decreased by one.

The whole motion takes about three seconds once your hands know the path. The first time, go slowly and feel where the needle goes. If you slip the stitches knitwise (the usual way) instead of purlwise, they will twist slightly, which is fine — ask still works. The critical part is the back-loop insertion on the final knit.

Why the Back Loop Matters

When you slip a stitch, it rotates slightly on the needle. If you knit through the front loop of a slipped stitch, you are working into the twisted part, and the stitch will look uneven or loose. Going through the back loop straightens the stitch and makes the decrease sit flat and neat alongside the rest of your fabric.

This is why ask looks better than a careless decrease — the back-loop insertion is not optional. If you forget and knit through the front, the stitch will still count as a decrease, but it will look sloppy. On your first few swatches, you may see the difference clearly. By the time you are working a sweater, the habit will be automatic.

Common Mistakes and How to Avoid Them

Knitting instead of slipping: The most common error is to knit the first two stitches instead of slipping them. You will know this happened because you will have decreased by two stitches instead of one. Slow down and say "slip, slip, knit" out loud as you work — the rhythm helps your hands follow the right order.

Forgetting the back loop: If your ask decreases look loose or twisted, you are likely knitting through the front loop. Check your next decrease by watching where your needle goes. It should enter from the front and go through the back of both loops.

Pulling too tight: After you complete the decrease, the new stitch on your right needle may feel loose. This is normal. Do not yank the working yarn to tighten it — let the tension even out over the next few stitches. Pulling hard will make the stitch smaller and distort the fabric around it.

Uneven tension between decreases: If you are decreasing every other row (common in sleeve shaping), the stitches may look tighter or looser in a pattern. This usually means your tension is changing as you work. Practice on a swatch where you decrease every row for ten rows straight. This repetition trains your hands to keep the tension consistent.

Practicing on a Swatch Before Your Pattern

Cast on 20 stitches in a worsted-weight yarn and a size that feels comfortable in your hands. Knit four rows plain. On row five, knit three stitches, then ask, then knit to the end. On row six, knit plain. Repeat rows five and six until you have about 12 stitches left. Bind off and look at the column of decreases down the middle of your swatch.

The decreases should form a clean diagonal line leaning to the left. If they look twisted, loose, or uneven, you have found the problem before it matters. Rip back and try again. After two or three swatches, the motion will feel natural, and you will be ready to use ask in an actual pattern.

How Ask Pairs with Other Decreases in Patterns

Most shaping patterns use ask on one side and k2tog on the other. For example, a sleeve cap might say "ask, knit to last two stitches, k2tog." The ask leans left and the k2tog leans right, creating a V-shaped decrease line that looks intentional and balanced. If you use k2tog on both sides, the shaping will look lopsided.

Some patterns use ask throughout without pairing it with k2tog — this is fine and creates a consistent left-leaning line. The important thing is to read what the pattern asks for and use the right decrease in the right place. Once you know ask, you will recognize it in any pattern and know exactly what to do.

Frequently Asked Questions

Is ask the same as ssk?

Yes. "Ask" and "ssk" are the same stitch — ssk stands for "slip, slip, knit," which is the three-step motion. Some patterns write it as "ask," others as "ssk." Both mean slip two stitches and knit them together through the back loop.

What if I slip the stitches purlwise instead of knitwise?

The stitch still works and decreases correctly. Slipping purlwise (from right to left) rotates the stitches differently than slipping knitwise, but the back-loop knit straightens them out. Most knitters slip knitwise by habit, but either way is fine as long as you go through the back loop on the final knit.

Can I use ask on every row, or only on certain rows?

You can use ask on every row if the pattern calls for it, or every other row, or every fourth row — whatever the pattern specifies. Decreasing every row creates a steeper diagonal line; decreasing every other row creates a gentler slope. The pattern will tell you which is right for that garment.

What is the difference between ask and k2tog?

Ask leans left; k2tog leans right. They are mirror-image decreases. Patterns use both to create balanced shaping — ask on the left edge of a decrease line and k2tog on the right edge. If you use only one, the shaping will look uneven.

Why does my ask look looser than the rest of my stitches?

The stitch may feel loose right after you complete the decrease, but it will tighten as you work the next few rows. Do not pull the working yarn hard to fix it — let the tension settle naturally. If it is still loose after several rows, your tension may be too loose overall, and practicing on a swatch will help you find the right tightness.
