Knitting Decreases

Ever wonder how to make a perfectly straight decrease that doesn't lean left or right? That's the centered double decrease, also known as CDD or s2kp. I use it all the time in lace, hats, and even garment shaping, and once you learn it, you'll start spotting it everywhere too. In this post, I'll show you exactly how to knit it, step by step, with tips to keep it neat and easy. So grab your needles and let's knit together.

Not all left-leaning purl decreases are created the same way, but in the end, they will look identical, no matter how you knit them. While the SSP (Slip, Slip, Purl) is slightly cleaner than the p2tbl (purl 2 together through the back loop), both create a left-leaning decrease that mirrors the right-leaning p2tog (purl 2 together).
