This is a beginner friendly pattern and one you will make over and over again. Granny rectangles can be made into so many different patterns and designs. Just play around with the foundation row to get different size blocks. You can go really small or really long.

Made this blanket just before St. Patrick’s Day and love light blue and darker green. The name of the green yarn is Paddy Green, hence the blanket name. The green gives baby blanket the luck of the Irish. Use any color combo you like or just do it with one color. The choice is always yours, you are in charge of what you create at the end of the day. Hope you like this new crochet granny rectangle pattern.

If you want to refer back to my Basic Granny Rectangle Tutorial, please do so. I’m only posting the pattern today, no other fluff in this blog post.

Stitch Count

It bears repeating that if you want to change the size of the foundation chain, you need to adjust in multiples of 3 + 2. Count your foundation chain in 3’s and then add 2. If you need to make it longer, add in 3’s. If you need to make it shorter, subtract in 3’s. That’s the crochet formula for this stitch pattern.

This pattern is for a rectangle granny baby blanket. The main difference between a granny square and granny rectangle is just the shape. That’s the only thing that’s different. The stitch pattern is the same for the corners and sides for the most part. This pattern is based on the traditional granny square but shaped into a rectangle. It’s made up of granny clusters, these are three double crochet stitches in the same chain. You will get a rectangle granny blanket which is slightly different than a square blanket. This free pattern uses a simple variation of the classic granny square.

Cast on anywhere

When you start new rounds, you can start anywhere you like on the block. It doesn’t have to be on the corners. You also don’t need to flip your work but I noticed that as my work got bigger, it wasn’t laying flat. That’s when I decided to flip my work and it helped it lay flatter.

When your new granny rectangle crochet pattern is done, make sure the right side of the block is facing up. Look at the very center line of the block, don’t look at the granny clusters. You can see the foundation starting chain looks better on one side of the block. Use the side that looks best for the front of your work.

The rectangle shape is really perfect for baby blankets. I’m not done yet, still thinking of adding little pom poms that hang on all four corners.

Supplies Needed

  1. Yarn in Sample: Red Heart White, Red Heart Paddy Green, Red Heart Light Blue (one skein of each).
  2. Crochet Hook: Select your crochet hook size that matches the yarn weight you’ve chosen. My sample used a H or 5.00 mm crochet hook.
  3. Scissors: For changing colors of yarn only when you run out of a color.
  4. Yarn Needle: For weaving in ends.

Paddy Baby Blanket Crochet Pattern

I will be using crochet short abbreviations in this post. You will notice most of these basic stitches but let’s talk more about the Granny Cluster and Granny Corner.

Granny Cluster – A granny cluster is just 3 double crochet stitches in the same chain. These 3 double crochets are called a granny stitch or granny cluster. Technically, Granny Clusters are used everywhere on a block but for this pattern it’s used on the sides only. You simply place 3 double crochet stitches in the same chain or chain space, depending on what round you are on. I’ve got another term for the granny clusters used for the corners.

Granny Corner – A basic granny corner on any shape block (rectangle or square) is made up of 2 Granny Clusters with 2 chains in between. Those 2 chains create a chain space for the next round. This chain space is the actual corner of the block and allows you to turn direction with your work. Once chain for each side of your work. It makes sense when you break it down. Granny Corners are always the same for granny squares but are different in the first round of a granny rectangle. Because we are turning a foundation row into an oval shape, the first round corners require 3 Granny Clusters. It’s easy but I wanted to point this out.
