About this Pattern


If you’re looking for a blanket that doesn’t take months to complete, you’re in the right place. We use Bernat blanket yarn in our wavelength crochet blanket to not only work up fast but make a blanket your family will love to snuggle with.

With this project you’ll get to practice the wavelength crochet stitch, a reversible stitch that’s a great choice for all sorts of projects. Customize the color palette to your liking. Use only two colors for a more simple look or four colors for some variety.
