What is a Single Crochet Increase?

A single crochet increase (sc inc) or “crochet increase” is a technique used to add two single crochet stitches into the same space as one original stitch. This essentially increases the number of stitches in a row, project, or round – allowing you to shape it in interesting ways.

What is a Single Crochet Decrease?

A single crochet decrease (sc dec or sc2tog) is when you single crochet two stitches together to decrease the number of stitches in a row, project, or round. This technique is crucial for creating 3D shapes in crochet.

To decrease single crochet

Insert your hook into the first stitch
Yarn over and pull up a loop (two loops on hook)
Insert your hook into the second stitch
Yarn over and pull up a loop (three loops on hook)
Yarn over and pull through all three loops.
