Pattern Description:
The C2C (corner-to-corner) granny square reimagines the classic granny design by working diagonally rather than from the center out.
This creates a fresh, modern look with a playful, textured stitch pattern. Ideal for blankets, cushions, and accessories, it’s a fun technique perfect for using multiple colors or a single shade.
Materials Needed & Measurements:
- Yarn: Choose your favorite yarn in one or several colors. Solid or variegated yarns both look great with this diagonal texture.
- Yarn Weight: DK (Light worsted / Category 3) is recommended.
- Hook: 4mm crochet hook (or hook size that suits your yarn and preferred tension)
- Notions:
- Yarn needle for weaving in ends
- Scissors
- Measurements: A typical C2C granny square made with DK yarn and a 4mm hook measures about 6-7 inches (15-18 cm) across, depending on the number of rows and tension. You can easily adjust the size by adding or removing rows.
Stitches & Abbreviations Used
- ch: chain
- dc: double crochet (US terminology)
- sl st: slip stitch
- sp: space
- beg block: starting block at the beginning of a row
- block: a group of 3 dc worked into a space
Instructions for Making the C2C Granny Square Pattern:
This pattern is worked diagonally, building up blocks row by row until you reach your desired size, and then decreasing to finish the square.
Foundation & Increase Rows
- Row 1: Ch4 (counts as first dc + ch1 sp). Work 3 dc into the 4th ch from hook. This forms your first block.
- Row 2: Ch4, turn. Work 3 dc into the first ch1 sp (this is the increase). In the next ch1 sp (which is at the end of the previous row), sl st to join, ch3, and work 3 dc into the same space. You now have two blocks in this row.
- Row 3: Ch4, turn. Work 3 dc into the first ch1 sp. In the next ch1 sp, sl st, ch3, 3 dc. Repeat from to until you reach the end of the row.
- You should now have three blocks in this row.
Continue Increasing
- Keep repeating this process, starting each row with ch4, 3 dc into the first ch1 sp, then joining into each subsequent ch1 sp across the row with sl st, ch3, and 3 dc.
- Each new row will add one more block than the previous row, making the square grow diagonally.
Decide When to Start Decreasing
Once your square is the desired width from corner to corner, you’ll stop increasing and begin decreasing.
Decrease Rows
- To decrease: At the end of a row, instead of starting with ch4, turn and sl st into the top of the last 3 dc from the previous row until you reach the next ch1 sp.
- Then ch3 and work 3 dc into that ch1 sp.
- Continue working across the row as before, but don’t add an extra block at the end.
- Repeat this decrease on each row: sl st across to the next ch1 sp, ch3, 3 dc, then work across the row.
- Each decrease row removes one block from the width, gradually narrowing the square until only one block remains.
Finishing
Fasten off when you complete the last block. Weave in all ends securely with a yarn needle.
Tips & Variations:
- Experiment with color changes: alternate every row, use self-striping yarn, or fade from light to dark.
- Adjust hook size or yarn weight to make larger or smaller squares.
- Use these squares to build patchwork blankets, bags, or even garments.
- For a smooth edge, finish with a round of single crochet all around the square.
Final Thoughts:
The C2C granny square is a playful twist on tradition, perfect for crocheters who love geometric designs and creative color play.
Once you learn the technique, you’ll enjoy making cozy, textured squares that look stunning in every project.
