Decreasing Stitches

A decrease (abbreviated dec) in knitting is a reduction in the number of stitches, usually accomplished by suspending the stitch to be decreased from another existing stitch or by knitting it together with another stitch.

Decreases are useful in shaping the edges of knitted pieces, and also in lace patterns. The correct decrease will help the fabric slant in the direction it should.
Some decreases slant left and other slant right; pattern instructions sometimes specify which type you should use. Sometimes it's not vital at all. If a pattern doesn't specify, you can use k2tog decrease.

Other times, especially in lace patterns, the correct decrease is important because it impacts which way the fabric biases or slants. Lace pattern stitches will specify which decrease to use when.

These decreases slant to the left:
* ssk (slip, slip, knit)
* k2tog tbl (knit 2 stitches together, through the back loops)
* sl1, k1, psso (slip 1, knit 1, pass stitch over) also known as skp.

These decreases slant to the right:
* k2tog (knit two together)
* k1, sl1, psso (knit 1, slip 1, pass stitch over) also know as ksp. This is an unusual decrease which often better mirrors the SKP when the slipped stitch has been sure distorted.

Double Decreases:
*sl1, k2tog, psso*, This is a left double decrease
*sl2, k1, p2sso*, This is a centered double decrease
*K3tog* This is a right double decrease

Single Decreases
One-stitch decreases are used to shape sleeves, armholes and necks.
When more than one stitch is suspended from a stitch, they can hang in different orders. For example, the first stitch could be on top of the second stitch (when seen from the right side) or the reverse, leaning to the left or the right. The order of stitches is important, both for appearance and for the way it pulls the fabric.

Knit 2 Together (k2tog):
The most common right-slanting decrease. Is often combined with the ssk or slip, slip knit, which slants to the left, to make even decreases on two sides of a knitted object.
The knit two together decrease is made by working into two stitches at the same time, as though they were one stitch. Completing a k2tog creates a decrease in your knitting because where once there were two stitches; there is now only one stitch.
If you are decreasing evenly on both sides of your fabric, you can use this decrease on the left side of the front of the garment. On the right side you can use a left slanting decrease such as ssk (slip, slip, knit).
1. To Knit the two stitches as if they were a single stitch, insert right needle through 2 stitches at once from left to right.

2. and complete knit stitch as usual. (video).

You can do the same thing with purl stitches; then it is known as purl two together (p2tog).


Purl 2 Together (p2tog):
This decrease slants to the right when viewed from the knit side (is the purl-side method of the knit two together increase). It’s counterpart is the ssp (slip, slip, purl).

1. To Purl the two stitches as if they were a single stitch, insert the right needle through the next two stitches as if to purl.
2. Work them the exact same way you would if you were purling just one stitch.


Slip Slip Knit (ssk): video
The most common left-slanting decrease. This decrease slants to the left. Is usually paired with knit two together on knit rows.
Slip two stitches from the left needle to the right needle (one at a time). Insert left needle from left to right into the front loops of both slipped stitches and knit them together through the back loops.
If you are decreasing evenly on both sides of your fabric, you can use this decrease on the right side of the front of the garment. On the left side you can use a right slanting decrease such as k2tog (knit 2 together).
1. Slip one stitch knitwise, then slip a second stitch knitwise.
2. Insert left needle through the front of both slipped stitches from left to right.
3. Complete knit stitch by wrapping yarn around right needle and pulling through.


Slip Knit Pass (skp):
Also known as Slip, Knit, Pass the Slipped Stitch Over (sl, k, psso).
This is a single decrease and it slants to the left that gives basically the same effect as an SSK. Use them interchangeably, whichever method you prefer.
To complete this technique slip one stitch, knit the next, pass the slipped stitch over the knit one.


1. Slip one stitch knitwise.

2. Knit the next stitch.

3. Then pass the slipped stitch over the knit one...


4. ...and off the needle.


Slip Slip Purl (ssp):
This decrease slants to the left. This is quite similar to the ssk, but on the purl side. It’s coordinating decrease is p2tog (purl two together) which slants to the right.
This decrease needs to be done on the reverse side (the purl row), which usually means a row later or earlier than when it is called for. If you're knitting in the round, you can't use this decrease, since the purl-side never faces you.
(On the purl row) Slip 1 k-wise, slip another k-wise. Return slipped sts to left needle. p2tog tbl: Insert right needle up into back loops of the two stitches and purl them together from this position.

1. Slip one stitch knitwise.
2. Slip a second stitch knitwise.
3. Return these two slipped stitches back to the left needle.
4. Insert the right needle into these two stitches through their back loops.
5. Purl these two stitches together.


Double Decreases
(also known as DD or dec2) Is used frequently in lace patterns.

Slip 1 Knit 2 Together Pass over (sk2p):
Also Known as sl1, k2tog, psso.
This is a left-slanting double decrease

1. Slip one stitch knitwise.


2. Insert right needle through 2 stitches at once from left to right and complete knit stitch as usual.


3. Here you can see the first decrease done.


4. Pass your slipped stitch over the single stitch left after knitting the two stitches together and off the needle.



5. This creates a left-slanting double decrease, decreasing from three stitches to one stitch.



Slip 2 Knit 1 Pass 2 over (s2kp2):
Also known as sl2, k1, p2sso.
This is a centered double decrease.

Slip two, knit one, pass two over. Slip two stitches together as if to knit, knit one stitch, then pass the two slipped stitches over the stitch you just knit. This results in a centered double decrease.

Knit 3 Together (k3tog): video
This is a right-slanting double decrease.
The knit three together decrease is made by working into 3 stitches at the same time. To work a k3tog, insert your right needle into the first 3 stitches and knit them together as 1 stitch. It decreases 2 stitches, where once there were three stitches; there is now only one stitch.

Slip, Slip, Slip, Knit (sssk): video
slip, slip, slip, knit 3 slipped stitches together. A double decrease.

1. Slip one stitch knitwise, then slip a second stitch knitwise, and third stitch knitwise.
2. Insert left needle through the back loop of slipped stitches from left to right.
3. Complete knit stitch by wrapping yarn around right needle and pulling through.
