Today I want to share my tutorial for how to do a Half Double Crochet Decrease, which is also known as the HDCDEC, DC2TOG or Half Double Crochet Two Together Stitch. This stitch is a variation of the Half Double Crochet Stitch and is regularly used as a way to reduce two Half Double Crochet stitches to a single Half Double Crochet Stitch. I’ve got both a photo and video tutorial for us today so let’s grab our hooks and our yarn and let’s learn how to crochet the Half Double Crochet Decrease Stitch or HDCDEC.

You can use any hook and yarn combination with this stitch but today I’ll be using a Furls Odyssey 5.5mm crochet hook and a Brava Worsted Weight Yarn from We Crochet.

**You may see HDCDEC or HDC2TOG used to describe this same stitch in different patterns. I tend to stick to HDCDEC in my own designs but know that if you see HDC2TOG in other patterns, they tend to mean the same thing.
