Granny Square Basics: Mastering the Essential Crochet Stitch

The heart of this project lies in the classic granny square. Here’s a quick refresher (or beginner’s guide) to the basic stitch pattern:

  • Chain (ch): The foundation of many crochet projects.
  • Slip Stitch (sl st): For joining rounds or creating a closed ring.
  • Double Crochet (dc): A taller stitch, often used in patterns like this one.
  • Half Double Crochet (hdc): A slightly shorter stitch for a tighter fabric.

Choosing Your Colors: Personalizing Your Granny Square Cardigan

Here’s where you get to let your creativity shine! Granny square projects are perfect for using up leftover yarn or coordinating a specific color palette. Consider solid colors, variegated yarns, or a mix of both for a unique look. The possibilities are endless!

Assembling Your Squares: Joining Techniques for a Seamless Look

Once you have a collection of granny squares, it’s time to join them. There are several methods, but we’ll use a simple slip stitch join for a clean and sturdy finish.

Crafting the Perfect Fit: Shaping Your Granny Square Cardigan

While the granny square cardigan has a naturally relaxed fit, some shaping is involved. We’ll create sleeves and a body with easy increases and decreases to ensure it drapes beautifully.

Finishing Touches: Adding Flair to Your Granny Square Cardigan

Make it truly your own! Add a border, try different edgings, or even incorporate pockets or a hood. The options to customize your cardigan truly are limitless.

Written Pattern: Cozy Granny Square Cardigan

This written pattern details the creation of a cozy granny square cardigan for women. Difficulty level is considered beginner+, assuming familiarity with basic crochet stitches like chain (ch), single crochet (sc), double crochet (dc), and slip stitch (sl st).

Remember, this is just an overview! Here’s a full written breakdown, inspired by the wonderful tutorial created by @BrennysCrochet1111 on YouTube ([]). I highly recommend her video ( for a more visual guide.


  • Make a 4″ x 4″ granny square using your chosen yarn and hook to check gauge. Adjust hook size if needed.

Granny Square:

  1. Round 1: Ch 4, join with a sl st to form a ring. Ch 3 (counts as first dc), 2 dc in the ring, ch 2, 3 dc in the ring, ch 2, 3 dc in the ring, ch 2, 3 dc in the ring, sl st to join (corner made).
  2. Round 2: Ch 3 (counts as first dc), 2 dc in the corner ch-space, ch 2, 3 dc in the next ch-space, ch 2, 3 dc in the next ch-space, ch 2, 3 dc in the next ch-space, ch 2, 3 dc in the corner ch-space, sl st to join. (Corner made).
  3. Rounds 3- desired size: Repeat Round 2, increasing corner spaces by 2 ch at the beginning of each corner section.
  4. Finishing: Fasten off and weave in ends.

Making the Granny Squares:

  • Crochet the desired number of granny squares, considering the size you want for your finished cardigan.
  • You can make all the squares the same color, or create a fun, multicolored design!

Joining the Squares:

  1. Lay the squares out in the desired layout for your cardigan back and front.
  2. Using a yarn needle and yarn in a contrasting color (optional), join the squares together with a simple slip stitch join.
  3. Sew the squares together along the sides that will form the seams of the cardigan.

Shaping the Body:


  1. Leave out a designated number of squares on each side for the sleeves (typically 3-4 squares).
  2. On the armhole edge, join the top squares together using a decreasing technique. Here’s an option: Skip the last two stitches of one square, then sl st through the top two stitches of the next square. Repeat for all armhole squares.


  1. Once the armholes are shaped, join the remaining squares across the top of the back using a slip stitch join.

Body Shaping (Optional):

For a more fitted silhouette, you can add a slight decrease at the waist. Here’s a suggestion:

  1. On a designated row across the desired waistline, skip the last stitch of each granny square before joining them together.

Finishing Touches:

  1. Edging: Crochet a border around the entire cardigan for a polished look. Choose your favorite edging stitch, like single crochet or a decorative pattern.
  2. Buttons & Buttonholes: Add buttons and buttonholes for closure (optional).
  3. Weave in Ends: Neaten your project by weaving in all loose yarn ends.

Congratulations! You’ve crocheted a beautiful and cozy granny square cardigan.


  • Use stitch markers to keep track of your corners and joining points.
  • Block your finished cardigan to even out the stitches and achieve a professional look (optional).

Remember, this pattern is a guideline. Don’t be afraid to experiment with colors, square sizes, and additional embellishments to make your cardigan truly unique!
