Blocking
Block all squares to 6 inches square. This ensures even seams and a professional finish. To block, wet the squares, gently squeeze out excess water, and pin them to the correct dimensions on blocking mats. Allow them to dry completely before joining.
Joining Squares
Arrange your 36 squares in a 6x6 grid. For a dynamic, scattered agate pattern, alternate the starting color (A or B) across the grid. This creates visual interest and mimics the natural variation in gemstones.
Using color D and a 5.5mm hook, join squares with a single crochet seam through the back loops only. Start by joining squares in rows (join 6 squares per row), then join the rows together. This method creates a flat, nearly invisible seam on the front.
Border
Once all squares are joined, add the finishing scalloped border:
Round 1
Join color A in any corner of the blanket. Chain 1, work 1 sc in each dc and 1 sc in each ch-1 space around the entire blanket, working 3 sc in each corner. Join with slip stitch to first sc.
Round 2
Chain 1, work 1 sc in each sc around, working 3 sc in each corner. Join with slip stitch.
Round 3
Chain 1, *skip 1 sc, work 5 dc in next sc, skip 1 sc, slip stitch in next sc* repeat from * to * around, adjusting at corners as needed to ensure a smooth scallop. Fasten off and weave in all ends.
Your Blue Agate blanket is complete! The silver shimmer yarn will catch the light beautifully, and the textured clusters create a plush, cozy surface perfect for snuggling. This gemstone-inspired throw makes a stunning gift or a luxurious treat for your own home.
