Decreasing means reducing the number of stitches on your needles — it is what shapes the crown of a hat, a sleeve, a neckline or a shawl. In this video we work through it step by step and, above all, how to choose the right decrease depending on which way you want it to lean.
The two basic decreases
- Knit two together (k2tog). Insert the needle into two stitches at once and knit them as one. The decrease leans to the right.
- Slipped decrease (ssk / skpo). Slip one stitch without working it, knit the next, then pass the slipped stitch over. The decrease leans to the left.
- Use them as a pair. On sleeves and necklines you put the left-leaning decrease on one side and the right-leaning one on the other, so the shaping mirrors.
- Space the decreases. If the pattern asks for several decreases in one round, spread them evenly so the fabric doesn’t pucker.
- Count after each decrease row. It is the fastest way to catch a mistake before the work grows.
Common mistakes
- Always using the same decrease. The result looks skewed on symmetrical pieces such as sleeves.
- Decreasing right at the edge. Leave one or two stitches of margin so the seam stays clean.
- Decreasing too fast. If the fabric pulls or points, spread the decreases over more rows.
Frequently asked questions
What is the difference between the two decreases?
Only the lean. K2tog leans right, the slipped decrease leans left. Both remove exactly one stitch.
Can I decrease on a purl row?
Yes, both decreases have purl-side versions. In flat knitting they are used when the pattern specifically calls for them.
Why do I get a line of little holes?
Usually tension: the stitch next to a decrease loosens. Give the yarn a slight tug on the stitch right after the decrease.
