Decreases combine two stitches into one to shape your work. That is how a beanie crown closes, how a bootie toe rounds off, and how an amigurumi head tapers. Every crochet pattern uses them, and most patterns assume you know how.
Laura from HappyBerry Crochet runs through six decreases in one sitting. The traditional sc2tog, hdc2tog, and dc2tog are the standard moves most patterns reference. The invisible versions of each are the same finished width but smoother across the top, because you skip a step and only catch the front loop of the next two stitches. Once you see the difference side by side, it is hard to unsee.
Pair this with how to increase in crochet for the other half of shaping. If you are still building muscle memory on the base stitches themselves, brush up on how to single crochet, how to half double crochet, and how to double crochet first. The decrease moves below build directly on those stitches.
The three decreases and where they show up
| Decrease | Loops before final pull | Where you meet it |
|---|
| sc2tog | 3 | Amigurumi, beanie crowns, dishcloth corners |
| hdc2tog | 5 | Hats, slippers, cowls worked in hdc |
| dc2tog | 3 | Garments, shawls, granny-style shaping |
The invisible decrease for amigurumi
Stuffed toys are where the invisible decrease earns its keep. An amigurumi head can take 30 or more decreases in a few rounds. Do them all the traditional way and the top of the head gets a ring of little lumps, with a gap beside each one where stuffing peeks through.
Working through the front loops only keeps the fabric tight and flat, so the curve stays smooth. If you are making your first toy, see how to crochet amigurumi - it leans on this move in every closing round.
Reading "dec" in a pattern
Pattern writers are not consistent. "Dec", "sc2tog" and "sc dec" usually mean the same thing in a single crochet pattern. "Inv dec" means the invisible version. Watch the context: in a dc pattern, "dec" means dc2tog, not sc2tog. A line like "*sc 2, dec* 6 times" means work two single crochet, then one decrease, and repeat that group six times.
US and UK terms matter here too. A UK pattern that says "dc2tog" is asking for what US patterns call sc2tog. Check which terms the designer uses before you start.
Counting stitches after decreasing
Each decrease uses two stitches and leaves one, so every decrease takes one stitch off your count. The example above starts with 24 stitches: each group uses four stitches and leaves three, so you end with 18. Most patterns print that number in brackets at the end of the round.
Count after every decrease round, not every third. A stitch marker in the first stitch of the round makes it quicker.
Common decrease mistakes
- Holes beside the decrease. Your traditional decreases are loose. Switch to the invisible version or pull the loops a little snugger.
- Lumps on the surface. Normal for traditional decreases in the round. The invisible decrease removes them.
- Count keeps coming up high. You worked into one stitch instead of two, which makes a regular stitch.
- Count keeps coming up low. You skipped a stitch between decreases. Recount the plain stitches in each group.
