🌟 Introduction
Introduce a splash of vibrant lace into your next project with the Azure Windowpane Square! This unique motif cleverly combines a traditional square shape with circular elements, creating the visual effect of open “windowpanes” surrounded by delicate lace. It’s a wonderful intermediate-level pattern, perfect for making afghans, scarves, or light summer shawls by joining multiple squares together.
Skill Level: Intermediate
Finished Size (approximate): 6 inches x 6 inches (15 cm x 15 cm) square, when using thread.

🧵 Materials & Gauge
✨ Materials Needed
- Yarn/Thread: Approximately 40-50 yards of DK Weight (Light Worsted/8-ply) cotton yarn or Size 3 Crochet Thread for a denser finish, or Size 10 Cotton Thread for a more delicate lace. (The sample is a bright turquoise blue.)
- Hook: Size E/4 (3.5 mm) crochet hook (for DK yarn) or Size 1 (2.75 mm) (for Size 3 thread), or size needed to obtain gauge.
- Notions: Stitch markers (for corners), small sharp scissors, tapestry needle for weaving in ends, and T-pins for blocking.
📏 Gauge (Crucial for Sizing!)
- Rounds 1-4 (Center) should measure approximately 1.5 inches (4 cm) square.
- Crucial Check: Your square must lay perfectly flat. If it’s starting to bow or ruffle, adjust your tension or hook size.

✂️ Finishing & Blocking
🧺 Blocking is Essential!
- Wet Blocking: Blocking is mandatory to open the lace and ensure the square shape is crisp and flat.
- Soak the square thoroughly in cool water.
- Gently squeeze out excess water.
- Pin the square out firmly onto a blocking board, making sure the four corners are pulled into sharp 90-degree angles. Pin out the circular arches to open them up.
- Allow the motif to dry completely before unpinning.
✨ Conclusion
Weave in all your ends securely on the back of the work.
Congratulations! You have created the stunning Azure Windowpane Square, ready to be the start of a truly beautiful project.
