I am so glad you are crocheting along with me on this colorful hexy journey! Now that all our crochet hexagons are attached, it’s time to add the finishing touch.
This granny hexagon crochet edging pattern fills in the V-shaped valleys between joined hexagons to create a straighter edge around your blanket. The first part of the edging fills in those spaces, and then four simple rounds create the colorful granny-style border.
If you’re just finding this tutorial and want to make the complete blanket, visit my hexagon crochet blanket pattern page, where I’ve gathered all the patterns and tutorials you’ll need in one place.

I debated for a while how I wanted to finish off my blanket … did I want to keep the pointed edges of the hexagons or fill them in to make a straight edge? In the end, I decided to straighten the edges by designing this pretty crochet border that fills in those granny valleys as you work around the afghan.
Keep in mind that I laid out my motifs in the shape of one large hexagon, so I didn’t have any half-hexagons to fill in along these edges—only the V-shaped valleys.

How to Crochet the Granny Hexagon Edging
The first round consists of 3 steps, which will fill in the valleys where the hexagons were joined.
Step 1
Using the same color used to join your hexagons, join yarn in the ch-1 sp from Round 4 at the top peak of any hexagon (as worked in the granny hexagon crochet pattern). Ch 1 (does not count as a stitch), work 1 sc in same ch-1 sp, ch 2, work 1 sc in next ch-2 sp along the side of the hexagon, ch 2, work 1 sc in next ch-2 sp along the side of the hexagon, work 5 dc in ch-1 sp at the bottom where two hexagons were joined, work 1 sc in the next ch-2 sp along the edge of the opposite hexagon. Turn.
Step 2
Ch 2 and work 1 sc in next ch-2 sp along edge of opposite hexagon (counts as dc), work 1 dc in next st, 1 dc in next st, 2 dc in next st, 1 dc in next st, 2 dc in next st, Sl st in sc that was worked in the first ch-2 space of Step 1. Turn.
Step 3
Ch 1, drop loop from your hook and pick it up through the first ch-2 sp made in Step 1, work 1 sc in same ch-2 sp, ch 1, skip first st, *work 1 sc in next st, ch 1 and skip next st, rep from * twice more, work 1 sc in ch-2 sp that first sc of Step 2 was made, ch 1.
Now repeat Steps 1 through 3, starting with 1 sc in the top peak of the next hexagon. Repeat across.

I hope I didn’t lose you! I know it seems tricky, but once you “get it,” it will be a breeze, and I think you will be very pleased with how pretty it is.
Once you’ve filled in all those little valleys, the hard part is done! The next four rounds create the colorful crochet border and are easy peasy to work. You can even use these rounds on other granny-style blankets.
Finish the Crochet Blanket Border
Round 1: Join next color in any ch-1 sp from our “fill in” round just done. Ch 3 (counts as dc), work 1 dc in same ch-sp, work 2 dc in next ch-sp, and in each ch-sp around the blanket, work [2 dc, ch 2, 2 dc] in each corner; join and fasten off.
Round 2: Join next color between any 2 dc groupings, ch 1 (does not count as a stitch), work 1 sc between the same dc grouping as join, ch 1, *work 1 sc between the next 2 dc groupings, ch 1, repeat from * around, working [1 sc, ch 1, 1 sc] in each corner space, join and fasten off.
Round 3: Join next color in any ch-1 sp, ch 3 (counts as dc), work 1 dc in same ch-sp, work 2 dc in next ch-sp and each ch-sp around blanket, working [2 dc, ch 2, 2 dc] in each corner, join and fasten off.
Round 4: Join next color between any 2 dc groupings, ch 1 (does not count as a stitch), work 1 sc between the same dc grouping as join, ch 1, *work 1 sc between next 2 dc groupings, ch 1, repeat from * around, join and fasten off.

So many of us are having difficulty with “filling in the valleys” on RECTANGULAR shaped afghans. Do we just tie off one side [leaving a flat corner] and re-attach yarn in a peak of the next side? I tried several times to develop a neat edge for this round and I’m hopelessly lost! Major S O S, here!!!
Hi Michele 🙂 I played around and came up with a half hexagon pattern that would work well here. Keep an eye out for that post coming soon.
This is what I was going to say:
I made a prayer shawl using hexagon grannies. Each of my hexagons have 5 rounds (2 more than yours). My prayer shawl has 38 hexagons over 4 rows (Row 1 has 11, Row 2 has 10, Row 3 has 9, and Row 4 has 8). I really like the edging you did for your blanket. Do you have any suggestions for how I can modify this for my prayer shawl? I’ll appreciate any help you can provide. Thank you.

Hey…so I think I followed the pattern wrong. I think I am just now realizing that it is supposed to be a circle, but my afghan is a rectangle. How do I do the edging on it? I really love it, but I want to finish it!
Hi Elizabeth 🙂 You can follow my edging pattern for the edges that have that little valley. You will have to look up a half hexagon pattern online to fill the larger spots. Hope that helps!
Okay, so I am almost finished with this afghan. I am using a multi-shades of blue yarn with turquoise as the outer color (instead of white). My next task is trying to figure out how to do the edging. In the points you[‘ve included instruction for how to do it, but you did not include instruction for the other part, the part that looks like a half a hexagon. It’s not the same shape on all four sides. Can anyone help me with directions for that?
Hi Linda 🙂 I didn’t use any half hexagons since I attached my hexagon motifs to form a hexagon shaped afghan as well.
hi
I would love to know how to fill the half hex spaces while doing the edging. I see how to fill the v spaces but not the half hexes. thank you.
