mosaic crochet blanket

The Lake Effect Throw crochet pattern features a simple mosaic crochet design that is easy to make and looks stunning. Crochet colorwork doesn’t have to be complicated!

We live near Lake Michigan, so we get lake-effect snow every winter. If you look at the weather radar it sometimes looks like stripes of snow clouds. As I started on this crochet project, it reminded me of that.

Mosaic Crochet for Beginners

This popular crochet colorwork technique can be used to make so many different eye-catching designs. I first designed something with this stitch technique in 2021 for the border of our Blanket Crochet Along that year.

This photo is from a different project.

Each row consists of a series of single crochets, chains, and double crochets. You will work 2 rows in each color which allows you to carry unused color yarn up the side of your blanket, significantly reducing the number of ends you need to weave in.

Double crochets are always worked into the skipped stitch 2 rows below in front of the chains.

Best Yarn for Crochet Blankets

Sometimes Red Heart Super Saver yarn gets a bad rap because it can feel a little scratchy to crochet with but it is one of my favorites to use for blankets. I find that after the blanket takes a trip through the washer and dryer it softens right up.

I used the color Aran for my main color and Sutherland Stripe for the coordinating color. I love the soothing blues and greens of the Sutherland stripe colorway. Self-striping yarn gives a great color effect on this blanket but it would look great in two solid colors also.

Since this blanket is worked primarily in single crochet stitches it ends up being thick and cozy without many “holes”. I love wrapping up in it on the couch in the mornings with my coffee.

Notes

  • Ch 1 does not count as a stitch
  • Carry yarn up the side of the blanket instead of cutting after each color change
  • To modify width ch multiple 10+9
  • To modify length do more or less rows – keeping in mind this will change the amount of yarn needed.
  • Mosaic double crochets are worked on the right side only.
  • Take care not to make your mosaic double crochets too tightly. They should be the same height as the single crochets within the row.

  2. Oh my gosh! I have been longing for a pattern for Sutherland Stripe! I love the colors in it, but have struggled to find a good way to show them off! I am truly as excited about this as the exclamation marks show!!!
