Fantastic Beautiful Flower Square Crochet Pattern

Welcome back to the hook! Today we’re tackling a beautiful project that combines a solid, textured center with an open, airy filet border. This square is perfect for learning how to transition from working in the round to creating a straight, squared edge, and it’s a stunning motif for any heirloom project.

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

✨ Materials & Gauge

Icon	Item	Notes
🧶	Yarn	Approx. 50–75 yards of a lightweight cotton or acrylic yarn (fingering, sport, or light worsted weight). Cotton works best for defined stitches like this. The white in the photo is very classic!
鉤	Crochet Hook	A hook size appropriate for your yarn. I recommend a 3.0 mm to 4.0 mm hook to achieve a soft but not overly loose fabric.
✂️	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 5) should measure about 2.5′′ across.

📌 Finishing and Blocking

Secure Ends: Fasten off your yarn and use your tapestry needle to carefully weave in all loose ends on the back side of your work.
Blocking (Essential!): To make sure your square is perfectly square and the lace detail is crisp and open, blocking is a must.
1. Dampen your square using cool water.
2. Gently pin the square to a flat, padded surface (like a foam board), pulling gently but firmly on all four corners to make sure the sides are straight and the corners are 90∘.
3. Allow the square to dry completely before unpinning.

You now have a beautiful Lacy Medallion Filet Square! What project will this lovely motif become—a throw blanket, a runner, or perhaps a pillow cover?
