Three decreases-- *knit 2 together *slip, slip, knit *3 stitch decrease
includes a how-to
This post is about 3 handy decreases.
The first, "Knit 2 together" (abbreviated "k2tog") slants to the RIGHT. K2tog decreases away ONE STITCH every time it is done.
The second decrease, "Slip, slip, knit" (abbreviated "ssk") slants to the LEFT. Like k2tog, ssk also decreases away ONE STITCH every time it is done.
In lots of garments, paired decreases are used: k2tog AND ssk to make raglan decreases, v-necks (and other shapings too, like hat tops, sock gussets, etc.)
A third type of decrease "3 stitch decrease" (abbreviated "3stdec") slants neither right nor left, but makes a STRAIGHT LINE. 3stdec decreases away TWO STITCHES every time it is done. It is used especially on the tops of hats where a flat top is wanted (tams, roll-brim shaped hats) or to make the flat bottom of a knitted bag.
Here are directions for each of the three decreases:



(In a future post, there will be a pattern for improved baby booties which uses all three of these decreases.)

Here are directions for each of the three decreases:KNIT 2 TOGETHER
(k2tog)

- PREPARATION: Insert right needle from left to right (knitwise) through the two stitches at the tip of the left needle. Draw the yarn through the loops.
- The FINAL RESULT: The LEFT stitch lies on top, the RIGHT stitch is hidden behind, and the decrease slants RIGHT. One stitch appears where 2 were before, so k2tog is a one-stitch decrease.
SLIP, SLIP, KNIT

- FIRST SLIP: Insert the right needle from left to right (knitwise) into the first stitch on the tip of the left needle, and slip the stitch onto the right needle.
- SECOND SLIP: Repeat same step with the second stitch
- KNIT TOGETHER THOUGH THE BACK LOOPS: Insert the left needle into the front of the 2 stitches previously slipped onto right needle. Draw the yarn through the loops from this position.
- The FINAL RESULT: The right stitch lies on top, the left stitch is hidden behind and the decrease slants left. One stitch appears where 2 were before, so (like k2tog) ssk is a one-stitch decrease.
3 STITCH DECREASE

- Inserting from left to right (knitwise), run right needle through TWO loops at tip of left needle and slip these two stitches onto the right needle. Knit the next stitch. Next, insert the tip of the left needle under the 2 slipped stitches and lift them OVER the knitted stitch. This is called "passing the slipped stitch(es) over" and is abbreviated "psso."
- If 3stdec looks like combination of k2tog and ssk, that's because it is. Like k2tog, the stitch behind the top stitch slants right; like ssk, there is also a left slanting stitch behind the top stitch. The two slanted stitches combine to pull the top (middle) stitch straight. One stitch appears where 3 were before, so 3stdec is a two-stitch decrease.

Fabulous!
These simple posts really work. Your more involved posts have provided me with some food for thought.
Keep it up!
Thank you SO much. These are wonderful instructions and great visuals!
thanks so much. i couldn't figure out why the k2tog and ssk was different until you explained. thanks again.
Fairly new to knitting and research unknown stitches on the web. Came accross a stitch 3-to-1 Decrease. Thissounds like the same thing. I will give it a try. Thanks
Thanks for the great pictures! They say a lot more than written instructions alone. One small criticism: to really have the middle slipped stitch be the "top" stitch, the knitter should slip the stitches backward: insert the right needle into the second stitch in on the left needle, then slip the stitch to its right. Knit the next stitch, then lift the two slipped stitches onto the knit stitch and you will see that the middle stitch ends up on top. The backward slipping feels weird but if you don't do this the right most stitch will end up on top and the k3tog will slant to the left.
Hi Liz--the direction for the 3 st dec do indicate to do as you have said--to insert the right needle KNITWISE (from left to right) into the two stitches on the tip of the left needle. That would indeed be "backwards" as you have said. Thanks for writing.

Hi there...thanks for this blog.It's very helpful. I am trying to knit some japanese lace/cable patterns and came across a 5 stitch central decrease. I can't find anywhere on line that describes how to achieve this. I assume it would be similar to the 3 stitch non-leaning but can figure our if it would the same with 5 stitches or not. Any ideas?
Hi Deb--sorry for the delay in responding, the comments sometimes hide from me--I am a ditz with the computer, evidently.
For a five stitch central decrease, there are several options.
1: treat the TWO stitches on either side of the central stitch as though they are ONE stitch each, then proceed as for a three stitch central decrease.
2. draw the OUTER stitch of the two flanking the central stitch over the INNER of the two stitches flanking the center stitch (a psso-like move) and then work the 3-stitch center decrease. Alternatively, try drawing the INNER over the OUTER--this makes an interesting pattern, also: more raised than the outer over the inner.
Try these variations on a swatch and see which you like best.

Best, TK
I'm experimenting with a 3-to-1 decrease that seems more "centered" to me. I'd be interested in hearing your opinion:
Slip the first 2 sts knitwise as you say in your method. Then ktbl the next st (knit through the back loop). Psso.
Going now to try your SYTK :)
