The crochet chevron stitch and the crochet ripple stitch are the same. You will see both names used in different patterns. So, don’t let this confuse you.
This stitch gives your projects a wonderful flowing pattern, or a ripple. It’s just lots of fun especially when it’s worked with different colors.
Most often this stitch is started in the foundation row and then used throughout the project.
I've heard the chevron/ripple stitch referred to as a hill and valley stitch. I really like that analogy because it makes it much simpler to understand. So, I'll share it with you here.
The crochet chevron stitch is created by basically working 2 corners repeatedly. The top of the hill is one corner and the valley is another corner. The top of the hill is made by increasing the stitches and the valley is made by decreasing the stitches. These hills and valleys are repeated through your work creating the chevrons or ripples.
Marking your increases and decreases with stitch markers can help you keep track of where those stitches need to be. This will make things go much more smoothly.
