How to Sew Granny Squares?

To sew granny squares, you can use various techniques, including the invisible seam, single crochet, reverse single crochet, slip stitch on the front side, slip stitch on the back side, and slip stitch and chain method.

The invisible seam, also known as the mattress or ladder stitch, is a popular choice for its neat finish on the front with sharp corners and barely noticeable stitches on the back.

Another option is the join as you go (JAYG) method, which involves attaching more granny squares to your join as you go.

Single Crochet Join

Single Crochet Join
Ready to learn how to join your granny squares with a single crochet seam? This technique adds texture and strength to your project while creating a bulky seam that’s perfect for those who want a more pronounced join. Here’s a step-by-step guide:

  1. Prepare your materials: Make sure you have your crochet hook and the yarn you’ll be using for the seam.
  2. Choose your starting point: Begin at a corner where two motifs meet, typically a chain 3 or a joining chain.
  3. Attach the yarn: Insert your hook through both motifs in the last corner chain and attach your yarn, creating a slip knot.
  4. Chain 1: Chain 1 to create a foundation chain for your seam.
  5. Single crochet in the same stitch: Insert your hook through the back loop of the next stitch on the first motif and the back loop of the second motif, then single crochet in the same stitch.
  6. Continue stitching: Repeat this process, inserting your hook through the back loop of the next stitch on the first motif and the front loop of the second motif, single crocheting in each stitch.

Remember to keep your tension consistent and your stitches even to create a strong and seamless join. This technique is great for adding texture and strength to your project while also being easy to master. Happy crocheting!

Slip Stitch Join

Slip Stitch Join

Slip stitch join is a popular method for crocheters to seam their granny squares together. This join is quick and easy, creating an invisible seam that’s subtle and flexible. The slip stitch placement is important for achieving a balanced tension and an almost seamless join. To perform a slip stitch join, you’ll need to line up your motifs with the wrong sides facing each other. Insert your hook through the back loop of the first motif and the front loop of the second motif, then slip stitch in each stitch, keeping the tension loose for a flexible seam.

This join is suitable for various projects, including clothing and accessories. It’s particularly useful for creating a neat and tidy seam that isn’t visible on the right side of the work. The flat crochet join, on the other hand, is a different technique that involves working through the back loops only of your stitches, which results in a flat seam.

When joining granny squares, it’s vital to block the motifs beforehand to make sure they’re of equal size and stability. Check the stitch counts for alignment and lay out the squares for the desired arrangement. The choice of join depends on the desired appearance, texture, and project requirements. For a textured seam, use a single crochet join, while for a flat seam, use a flat crochet join.

Remember to keep your tension relaxed when using slip stitches to join squares, as working too tightly may cause the squares to not sit nicely once joined.

Flat Crochet Join
