🌼 The Petal-Edge Granny Square: A Detailed Crochet Pattern

Welcome, yarn artists! Today’s motif is the perfect blend of floral charm and geometric structure. Starting with a dense, textured bloom at its heart, this square effortlessly transitions into a clean, decorative square edge using elegant petal shells. It’s a fantastic square for joining into blankets, pillows, or even delicate garment yokes.

This pattern is written using U.S. Crochet Terminology.

✨ Materials & Gauge

Icon	Item	Notes
🧶	Yarn	Approx. 50–75 yards of a sport or light worsted weight cotton yarn. Cotton thread (Size 10) also works for a smaller, crisp finish. The white color is very elegant!
鉤	Crochet Hook	A hook size appropriate for your yarn. I recommend a 3.0 mm to 4.0 mm hook for a standard size square.
✂️	Tools	Tapestry needle for weaving in ends, and a pair of scissors.
📏	Gauge	The finished square should measure approximately 5.5′′×5.5′′ after blocking. Gauge check: The solid center (after Rnd 3) should measure about 2′′ across.

📌 Finishing and Blocking

Secure Ends: Fasten off your yarn and use your tapestry needle to carefully weave in all loose ends on the wrong side of your work.
Blocking (Crucial!): To ensure your petals are crisp and the square is perfectly square, blocking is a must.
1. Dampen your square thoroughly.
2. Pin the square to a padded surface (like a foam board), pulling gently but firmly on the four corners and the outermost shell points to define the shape.
3. Allow the square to dry completely before unpinning.
