Do both cardigan halves work up the same way?

Yes, both halves follow the same hexagon motif and DC rounds. The only difference is at the end, where one half cuts its yarn and the other keeps it attached to begin seaming.

Why does one half keep the yarn attached?

Keeping that strand live means you can move straight into the shoulder seam without rejoining yarn. It also keeps the seam's color consistent since it is the same working yarn.

What happens if I lose count of my corner spaces in the first round?

Stop and count your clusters against the corner spaces before closing the round with the slip stitch. Getting six clusters and six corners even now saves you from a lopsided hexagon later.

Is the seaming done with a hook or a needle?

Both. The shoulder and top edge are joined with a slip stitch seam using your hook, while the center back seam is sewn afterward with a yarn needle.

In what order should I finish the cardigan?

Complete and seam the top edge first while the pieces are flat and easy to align. Then fold for the center back seam, weave in your ends, and turn the whole thing right side out.

How do I know how many extra rows to add before the sleeve opening?

Subtract your hexagon's row count from the target of 22 rows total. For example, a Size L hexagon with 18 rows needs 4 extra flat rows before the final cinching row.

About This Pattern

This one has a steady, building-block feeling, like watching a honeycomb take shape one corner at a time. Each hexagon starts small and tight, then opens out into something with real structure. There's a satisfaction in the geometry that makes this piece feel more architectural than the usual cardigan.

Your hands will spend a lot of time circling back to the same corner space, DC after DC, until the shape fills out. It asks for a rhythm more than speed: chain three, work the cluster, land in that chain-2 space, repeat. Then there's the quieter work of seaming two finished halves into one garment.

Picture this draped over the back of a chair by the front door, ready to grab on the way out. The hexagon panels give it a bit of visual texture even when it's just hanging there. It reads as handmade without trying too hard, the kind of piece that gets noticed in a quiet room.

Start each hexagon with a slip knot and a small chain joined into a ring to work your first round into.
Build six clusters of double crochet separated by six chain-2 corner spaces to form the hexagon's first round.
Close that round with a slip stitch into the top of your starting chain.
Work a second round of double crochet across each side, turning the corner with a [2 DC, chain 2, 2 DC] at every corner space.
Add flat rows corner-to-corner on the sleeve opening side until the hexagon plus added rows reaches 22 rows total, then work one cinching row of DC skipping every other stitch.
Chain one and cut the yarn to finish one cardigan half cleanly.
the matching half, keep your yarn attached instead of cutting it so you can seam straight from that strand.
Lay the two halves right side facing you and slip stitch across the entire top edge to join the shoulder and sleeve seam.
Fold the piece so the back edges line up, then sew the center back seam from the neck down to the bottom before weaving in ends and turning the cardigan right side out.
