My love for making crochet afghans has increased over the past few years. I released a variety of styles of crochet afghans in 2019, but I hadn't made a hexagon afghan before so I designed my first, the Succulent Spring Hexagon Afghan. One of my favorite parts of designing a crochet hexagon motif afghan was that it made a great project to take along with me on long car rides. The crochet hexagons were small enough to pack and to work on my lap. While crocheting and designing my first hexagon afghan, I knew it wouldn't be my last. The Sea Glass Hexagon Afghan is my second crochet hexagon afghan and I've already started a third hexagon design!

Beginners and seasoned crocheters alike will love that the Sea Glass Hexagon Afghan pattern uses simple crochet stitch patterns and a self-striping yarn to create visual interest in the design. This hexagon afghan pattern is simple enough that advanced beginners can successfully complete it and the combination of changing stitch patterns (and colors) will keep others from losing interest.
Pair it with a variegated or self-striping yarn, and all of the colorwork is done for you. Lion Brand Yarns Ferris Wheel self-striping yarn was perfect for this design. I don't know about you, but my favorite part of a self-striping yarn is that I'm not left with a bunch of ends to weave in. Although I really love the colors in the self-striping yarn, I didn't want the hexagons to get too busy so I chose to add a little white as a contrast to break it all up. But if you don't want to change colors like I did, I believe a solid colored afghan would be absolutely stunning as well!
THE YARN
For this crochet hexagon afghan, I chose Lion Brand Yarns Ferris Wheel and Vanna's Choice, which are worsted weight yarns. Ferris Wheel is a 100% acrylic roving yarn that is lightweight and has beautiful self-striping color ways that lend themself to an ombre effect. It is available in 12 gorgeous colors. Vanna's Choice is a 100% acrylic yarn that is available in 36 gorgeous colors. Although Vanna's Choice is classified as a Craft Yarn Council 4 / worsted weight yarn, I’ve found that it is on the lighter side of most worsted weight yarns.
For the Sea Glass Hexagon Afghan, I’ve combined several simple crochet stitches and the colorwork of the yarn to add visual interest. The size is easily customizable so you can make it smaller for a baby shower gift or larger for a wedding gift! Look at the layout graphic in the pattern below so that you can see where you could add or subtract hexagons to customize the size of your blanket.

Sea Glass Hexagon Afghan Instructions
12" Full Hexagon Instructions - Make 18
Note: Pay close attention to the joining instructions. I've joined most rounds into the BLO of the first stitch to help minimize the seam.
Tip! I highly suggest using locking stitch markers where noted. They will help to keep you on track while you crochet and they come in very handy when seaming the hexagons together.

Do not turn. Do not fasten off. Continue on to Edging the Unfinished Edge.
Edging the Unfinished Edge
In this section, you'll add a single crochet edge to the sides of the rows of the half hexagon.
Row 1 (RS / MC): Do not move the 4 SM you placed in Row 14, rotate your half hexagon so that you can work into the sides of the rows, work 1 sc in the side of each sc row and 2 sc in the side of each dc row across, I also added a sc in the ch-2 from Row 1. Do not join. (43 sts) Do not move the SM’s.
Fasten off. Weave in ends. Approximate length of the longest edge should be 13.25" (unstretched). Continue on to Layout & Seaming.
Layout & Seaming
Step 1: Use the layout shown in the schematic above to arrange your hexagons.
Step 2: Use locking stitch markers or scrap pieces of yarn to hold the hexagons together while you seam. Make sure to place the stitch markers in the middle single crochet at each corner to keep your hexagons lined up straight. See photos below.
Step 3: Use a 5.00mm crochet hook to work a flat slip stitch seam, work all vertical seams shown in red.
Flat Slip Stitch Seam Tutorial Click Here
Step 4: Using a flat slip stitch seam, work all horizontal zig-zag seams.
Weave in all ends. Continue on to Edging.
The photos above are of my Succulent Spring Hexagon Afghan, but the seaming process is the same.
Edging
Tip! If your edge starts to become wavy, go down a hook size or two until it's nice and flat. If your edge starts to cinch inward, go up a hook size or two.
Rnd 1 (RS/MC): Refer to the green arrow on the schematic from above, using a 5.50mm crochet hook and MC yarn, join yarn with a standing sc in the corner that the green arrow is pointing to then work in the direction of the pink arrow. Work 1 sc in each st around the afghan, except work 3 sc in each of the peaks at the top and bottom edge of the afghan and work a sc3tog in each valley along the top and bottom edge of the afghan. Do not join. Stitch count isn't crucial.
Rnd 2 (MC): Work 1 sc in each st around the afghan, except work 3 sc in each of the peaks at the top and bottom edge of the afghan and work a sc3tog in each valley along the top and bottom edge of the afghan. Join with a sl st to the first st of the round. Stitch count isn't crucial.
Rep Round 2 as many times as you'd like. The afghan edging shown in the photos only has 2 rounds.
Fasten off. Weave in ends. Professionally finish your afghan by blocking it. Click HERE for my Super Easy Blocking Tutorial. Add tassels, if desired (click here for tutorial).
