The double crochet ribbed stitch is easy to do. In this tutorial, the finished project has the same appearance in both front and back side. Create a dishcloth, scarf, headband, or even a mug cozy from this pattern.

This project can be made with any size yarn on any size crochet hook.

In this tutorial, I used DK-weight cotton yarn and size 4 mm crochet hook.
