How to Crochet Granny Squares Shoulder bag

Absolutely! Let’s go step by step. I’ll give you a detailed guide on how to crochet a Granny Squares shoulder bag, including materials, techniques, and assembly tips. I’ll make it clear enough for a beginner to intermediate crocheter to follow.


Materials You’ll Need

  • Yarn: Medium weight (worsted) yarn in multiple colors (for granny squares) + one neutral color for joining (optional).
  • Crochet hook: Size recommended for your yarn (usually 5.0 mm / H-8).
  • Tapestry needle: For weaving in ends and sewing squares together.
  • Scissors
  • Optional: Fabric lining and sewing needle for lining the bag.

Step 1: Make Granny Squares

Granny squares are the building blocks of your bag.

Basic Granny Square Pattern:

  1. Start with a magic ring (or chain 4 and join to make a ring).
  2. Round 1: Chain 3 (counts as first double crochet), then 2 dc in ring, chain 2, 3 dc in ring, chain 2 repeat 2 more times, join with slip stitch to top of chain 3.
  3. Round 2: Slip stitch to first corner space, chain 3 (counts as dc), 2 dc in corner space, chain 2, 3 dc in corner space, in next corner space: 3 dc, chain 2, 3 dc repeat around, join.
  4. Round 3 and beyond: Repeat corner pattern, increasing the sides by putting 3 dc clusters between corners. Continue until your square is the desired size (around 4–5 inches is common for a bag).

Make as many squares as you need. For a small shoulder bag, you might need 12–16 squares depending on size and layout.


Step 2: Arrange Your Squares

  • Lay your squares out in the pattern you like.
  • Decide the front, back, and sides of your bag.
  • Common layouts: 3×3 squares for the front/back, and 1×3 or 2×2 for sides.

Step 3: Join Squares

You can join squares in two main ways:

Method 1: Whip Stitch (sewn together)

  1. Place two squares right sides together.
  2. Use a tapestry needle and yarn, whip stitch through the edges.
  3. Join all squares to make the front and back panels and then the sides.

Method 2: Crochet Join

  1. Lay squares flat, edges touching.
  2. Using a slip stitch or single crochet, join edges by working through both loops along the edges.
  3. This gives a seamless look.

Step 4: Make the Bag Shape

  • After joining, you’ll have two panels (front/back) and side pieces if needed.
  • Step 4a: Attach sides to bottom: Join side squares to the front/back bottom edges.
  • Step 4b: Join top edges leaving the top open for the bag.

Step 5: Add the Strap

There are multiple ways to do this:

  1. Crocheted Strap: Chain to the desired length, then single crochet or double crochet back along the chain to make it sturdy. Sew each end to the inside top corners of the bag.
  2. Using a Ready-Made Strap: Sew the strap directly to the top corners of the bag.

Make sure the strap is strong enough to hold the weight of items you’ll carry.


Step 6: Optional Lining

  • Cut fabric slightly smaller than the bag size.
  • Sew the fabric inside the bag. This helps prevent small items from falling out and makes the bag sturdier.

Step 7: Finishing Touches

  • Weave in all loose ends.
  • Block the bag if needed (lightly steam or wet it to shape nicely).
  • Add buttons, zippers, or decorative elements if desired.

Tips for a Beautiful Granny Square Bag

  • Use contrasting colors for a bold look or shades of one color for a subtle style.
  • Keep your tension even, so squares match in size.
  • Reinforce strap connections, especially if using a light yarn.
  • Mixing square sizes can create a unique pattern.
