This tutorial is written using US terms however, if you’re more accustomed to the UK terms, here is a quick conversion for you:

US TermsUK Terms
CH = ChainCH = Chain
SC = Single CrochetDC = Double Crochet
SC3TOG = Single Crochet 3 Stitches TogetherDC3TOG = Double Crochet 3 Stitches Together
ST (s) = Stitch(es)ST (s) = Stitch(es)
YO = Yarn OverYO = Yarn Over

Materials Needed:

No special materials are needed to do the SC3TOG. It can be used with any yarn and hook combination.  I’m using WeCrochet Brava Worsted yarn in the colour Cornflower  which is a (4) worsted weight yarn and a 5.5 mm Crochet hook in this tutorial.

When learning basic crochet stitches (like single crochet, half double crochet and double crochet stitches), it is important to know the crochet decreases and increases for each of these stitches.

When doing the Single Crochet 3 Together Decrease, we are decreasing 3 single crochet stitches down to a single stitch.  This technique is used in a variety of decorative stitches and for shaping crochet pieces.

In my example here, I’ve started with a single crochet base (rows of regular single crochet stitches) however, this can be done working into a chain as well.

Insert hook into the first stitch (or chain). YO and pull up a loop.

Insert hook into the third stitch (or third chain). YO and pull up a loop.  You should have four loops on your hook.

​How to Minimize the Look of the Single Crochet 3 Together With the Invisible SC3TOG for Amigurumi Projects


When using the SC3TOG in amigurumi projects, a SC3TOG can be more noticeable on the right side of the fabric.  To minimize its appearance, work the single crochet three together stitch in the front loops only of the stitches of the previous row.  This makes the stitch less bulky.

I don’t recommend using the invisible SC3TOG when you’re crocheting a project where both sides of your fabric will show as it will disrupt the look of the wrong side of your fabric.
