Materials Needed: Gathering Your Ocean Treasures

Before you begin, ensure you have all the necessary supplies. The beauty of this pattern lies in its simplicity; you only need a few basic tools and a beautiful palette of yarn.

• Yarn: Worsted weight cotton or cotton-blend yarn in 5 colors. The approximate total yardage is 1200-1500 yards. Here’s a suggested palette:
  • Misty White (Color A)
  • Seafoam Green (Color B)
  • Pale Aqua (Color C)
  • Soft Sand (Color D)
  • Weathered Blue (Color E)
• Crochet Hook: 5.5 mm (I-9) crochet hook. This size is perfect for worsted weight yarn to achieve the correct drape and texture.
• Other Tools: A tapestry needle for weaving in ends and joining motifs, and a pair of scissors.

Gauge: 4 rounds of the hexagon = 4 inches across (measured from flat side to flat side). While gauge is important for size, this pattern is very forgiving. As long as your hexagons are consistent, your afghan will assemble beautifully.

Step-by-Step Instructions: Crafting Your Sea Glass Hexagons

This afghan is worked in individual hexagons and then joined together. We will make a total of 19 hexagons. Each one uses a combination of basic stitches and puff stitches to create that signature frosted texture. Let's break down the process.

Hexagon Motif (Make 19 Total)

Follow these rounds carefully. Each round builds upon the last to create the hexagonal shape.

Round 1: With Misty White (Color A), make a magic ring. Chain 3 (counts as a double crochet), work 2 double crochet (dc) into the ring, chain 2. *Work 3 dc into the ring, chain 2.* Repeat from * to * 4 more times. You will have 6 clusters of 3 dc and 6 ch-2 spaces. Join with a slip stitch to the top of the beginning chain-3. Fasten off Color A.

Round 2: Join Seafoam Green (Color B) with a slip stitch into any ch-2 space. Chain 3, work 2 dc in the same space, chain 1. *In the next ch-2 space, work (3 dc, chain 2, 3 dc), chain 1.* Repeat from * to * around, ending with 3 dc in the last ch-2 space, chain 2. Join with a slip stitch to the top of the beginning chain-3. (You will have 12 clusters of 3 dc and 6 corner ch-2 spaces). Fasten off Color B.

Round 3: Join Pale Aqua (Color C) with a slip stitch into the next dc (the first dc of the next cluster). Chain 3, work 2 dc in the same stitch, chain 1. *Work 3 dc in the next ch-1 space, chain 1. In the next corner ch-2 space, work (3 dc, chain 2, 3 dc), chain 1.* Repeat from * to * around, ending with 3 dc in the last corner space, chain 2. Join with a slip stitch. (You will have 18 clusters of 3 dc). Fasten off Color C.

Round 4 (Puff Stitch Round): This is the star of the show! Switch to Soft Sand (Color D). Join with a slip stitch into the next dc. Chain 2 (counts as a half double crochet, hdc). Now, work a puff stitch in the next dc: (Yarn over, insert hook, yarn over, pull up a loop, yarn over, insert hook, yarn over, pull up a loop, yarn over, insert hook, yarn over, pull up a loop. You will have 7 loops on the hook. Yarn over and pull through all 7 loops). Chain 1. Work a puff stitch in the next dc, chain 1. Work an hdc in the next dc, hdc in the next ch-1 space, hdc in the next dc. *Work a puff stitch in the next dc, chain 1, puff stitch in the next dc, hdc in the next dc. In the corner ch-2 space, work (hdc, chain 2, hdc). Work hdc in the next dc.* Repeat from * to * around, working puff stitches in pairs separated by a ch-1, and hdc in between. Join with a slip stitch to the top of the beginning chain-2. (You will have 12 puff stitches per hexagon). Fasten off Color D.

Round 5: Switch to Weathered Blue (Color E). Join with a slip stitch into the next hdc. Chain 3, work a dc in each stitch around, working (2 dc, chain 2, 2 dc) in each corner ch-2 space. Join with a slip stitch. (You will have approximately 42 dc per side and 6 corners). Fasten off Color E.

Round 6: Switch back to Misty White (Color A). Chain 1, work a single crochet (sc) in each dc around, working (sc, chain 2, sc) in each corner ch-2 space. Join with a slip stitch. Fasten off and weave in all ends. Your first hexagon is complete! Repeat this process to create all 19 hexagons.

Joining Your Hexagons: Assembling the Afghan

Once all 19 hexagons are complete, it's time to assemble them into a beautiful blanket. This is where the magic happens!

Arrange: Lay out your hexagons on a flat surface in a pleasing layout. A classic arrangement is 5 rows of 4 hexagons, with one extra to create an organic, slightly irregular shape. Play with the color placement to create a random, sea-glass patchwork effect.

Whip Stitch Join: With Weathered Blue (Color E) yarn and a tapestry needle, whip stitch the hexagons together. Work through the back loops only of the edge stitches, matching corners and edges carefully. This creates a nearly invisible, flat seam on the front. Join all hexagons in your chosen layout to form a large rectangle or organic shape.

Adding the Finishing Touch: The Scalloped Border

The border frames your beautiful work and adds a final layer of coastal charm.

Round 1: With Weathered Blue (Color E), join your yarn in any corner of the afghan. Chain 1, work single crochet (sc) evenly around the entire outer edge, working (sc, chain 2, sc) in each corner to turn. Join with a slip stitch.

Round 2: Switch to Misty White (Color A). Chain 1, work a sc in each sc around, working (sc, chain 2, sc) in each corner. Join with a slip stitch.

Round 3: Switch to Seafoam Green (Color B). Chain 1, work a reverse single crochet (also known as crab stitch) in each sc around, working (reverse sc, chain 2, reverse sc) in each corner. This creates a beautiful, twisted rope-like edge. Join with a slip stitch. Fasten off and weave in all ends.

Your Tidal Treasures Hexagon Afghan is complete! Lay it flat to admire the texture and colors. This blanket is a true labor of love, perfect for draping over a sofa, curling up with on a chilly evening, or giving as a cherished handmade gift. The combination of simple stitches and the rhythmic puff stitch pattern makes this a wonderfully meditative project. Happy crocheting!
