Decreases in knitting

In this article, I will show the main types of single and double decreases.

Decreases are often used to narrow knitted fabric in the horizontal plane. This technique reduces the number of stitches by one or more.

Classification of decreases

Depending on how many stitches are decreased at the same time, decreases can be single, double, triple, etc.

Depending on the direction in which the fabric is narrowed, decreases are divided into left-leaning and right-leaning decreases. When decreasing an even number of stitches (for example, double decreases), they can be central.

This article covers the following types of decreases:

Single decreases:

To make a single right-leaning decrease in a knit row, simply knit 2 stitches together. For this method of knitting decreases, the abbreviation K2tog is commonly used in literature. 

Single right-leaning decrease stage 1
Single right-leaning decrease stage 2

This stitch will lean to the right:

To make a single left-leaning decrease, you can use two methods:

First option – in the literature the abbreviation SSK is used – slip slip knit:

Insert the right needle into the first stitch as if to knit:

Single left-leaning decrease stage 1

Slip it onto the right needle:

Single left-leaning decrease stage 2

Slip the next stitch onto the right needle in the same way:

Single left-leaning decrease stage 3

Return these 2 stitches to the left needle in the new position:

Single left-leaning decrease stage 4

And knit them together:

Single left-leaning decrease stage 5

Second option (alternatively, result will be the same) – in the literature the abbreviation SKP is used (slip, knit, pass over):

Insert the right needle into the first stitch as if to knit:

Single left-leaning decrease stage 1

Slip it onto the right needle:

Single left-leaning decrease stage 2

Knit the next stitch:

Single left-leaning decrease stage 3 (SKP)
Single left-leaning decrease stage 4 (SKP)

And pass it over the slipped stitch:

Single left-leaning decrease stage 5 (SKP)
Single left-leaning decrease stage 6 (SKP)

The result is roughly the same.
The second method is somewhat simpler, but it’s a matter of personal preference.

In the literature the abbreviation K3tog is used. Simply knit 3 stitches together:

K3tog stage 1
K3tog stage 2
K3tog stage 3

Left stitch is on top, center – in middle and right – on bottom.

Central double decreases

They can be of two main types: the center stitch is in front and the center stitch is in back.

1. The center stitch of the 3 is in front (double decrease – DD or S2KP – slip, slip, knit, pass over)

Insert the right needle into 2 stitches together as if to knit:

DD stage 1

And slip them onto the right needle:

DD stage 2

Knit the third stitch:

DD stage 3
DD stage 4

And pass it over the 2 slipped stitches:

DD stage 5
DD stage 6

Center stitch is on top,

right – in middle,

and left – on bottom:

DD result

2. The center stitch of the 3 is in back.

In the literature the abbreviation SK2P ( slip, knit2, pass over) is used.

Insert the right needle into the first stitch as if to knit:

SK2P stage 1

And slip it onto the right needle:

SK2P stage 2

Knit the next 2 stitches together:

SK2P stage 3
SK2P stage 4

And pass the resulting stitch over the slipped stitch:

SK2P stage 5
SK2P stage 6

Right stitch is on top, 

left – in middle 

and center – on bottom:

SK2P - result

Left-leaning double decreases

There are also a few methods, let’s consider a couple of the most popular:

1. SSSK (slip, slip, slip, knit)

02:52 – in video

Insert the right needle into the first stitch as if to knit and slip it onto the right needle:

SK2P stage 2

Slip the second stitch as well:

SSSK stage 2

And slip the third stitch as well:

SSSK stage 3

Return all 3 stitches to the left needle in the new position:

SSSK stage 4

And knit the three stitches together:

SSSK stage 5

2. SSKP (slip, slip, knit, pass over)

03:19 – in video

Insert the right needle into the first stitch as if to knit and slip it onto the right needle:

SSKP stage 1

Slip the second stitch as well:

SSKP stage 2

Knit the third stitch:

SSKP stage 3

And pass it over the 2 slipped stitches:

SSKP stage 4
SSKP stage 5

You can see that the resulting left-leaning decreases look almost identical to each other.

Right stitch is on top, 

center – in middle 

and left – on bottom:

I hope this material was useful and helped you quickly and easily master the techniques of decreases.

Enjoy knitting!  🧶
