Each one is typed out whole and gets its own line.

This cardigan grows from two identical hexagons, each built outward from a chained ring to a six-cornered lace round, then squared off with solid double crochet before the sleeve is shaped and the body extended flat. Fold each hexagon along its diagonal, seam sleeve to neckline, then join the two halves at the back. Before starting, have both cakes of yarn wound and ready for the ombre effect, a 3mm hook, a measuring tape, and a yarn needle for the mattress-stitch seams to come.

Common mistakes and their fixes

Losing count of the six corners
Mark each corner chain space with a stitch marker after Round 1 so every later round's corner increase lands in the same spot.
Uneven ombre between the two hexagons
Start both cakes from the same point in the color sequence before beginning Round 1 on each hexagon.
Puckered underarm after the decrease round
Work the invisible decreases in Round 4 with even, slightly loose tension, and check the underarm lies flat before joining the corner.

Key to this pattern, 1 short form

Hexagon

Round 1

Make a slip knot and chain 4; slip stitch to form a ring; chain 3 (counts as first dc), make 2 dc in the center ring; chain 3 for the corner; make 3 dc into the center ring for the next side; repeat the corner and side pattern until you have 6 sides; chain 3 and slip stitch to the third chain of the starting chain.

Round 2

Lacy Pattern - Arch Row Chain 4, turn your work; make 1 dc in the corner space, chain 3, and make 1 dc in the same space; chain 1, dc in the first dc of the side, chain 1, skip one, dc in the last dc; chain 1, make (1 dc, chain 3, 1 dc) in the corner; repeat around and slip stitch to finish.

Round 3

Solid Double Crochet Row Chain 3 and turn your work; make 1 dc in each dc and chain space along the side; in each corner, make (2 dc, chain 2, 2 dc); continue around and slip stitch to finish; repeat this solid dc row two more times.Continue working the 4-row repeat (Row 1: Lacy Row; Rows 2–4: Solid Double Crochet Rows) until the piece reaches your desired sleeve length before beginning the sleeve shaping.

Round 4

Sleeve Shaping and Seam Chain 1 and turn your work; use invisible decreases (insert hook into front loops of two stitches, yarn over, pull through, yarn over, pull through both loops); work decreases along the sleeve section until the underarm corner; join corners with a decrease to close the underarm seam; continue single crochet decreases around and slip stitch to finish; fasten off and cut the yarn.

Round 5

Body Extension Attach yarn at the neckline corner; continue the 4-row repeat pattern across the three open sides, working back and forth; keep the corner increases (2 dc, chain 2, 2 dc) at the two body corners; add rows until the body reaches the desired length; fasten off.

Assembly, in order

Step 1Fold the hexagon in half, aligning the neck corner and sleeve end.
Step 2Cut yarn three times the seam length and thread it through a yarn needle.
Step 3Use mattress stitch to sew the edges together from sleeve to neckline.
Step 4Repeat the entire pattern for the second hexagon.
Step 5Place both pieces side by side and align the back edges.
Step 6Sew the back seam using the mattress stitch.
Step 7Weave in all yarn ends.

Check these before you start

  • Keep the corner chain-3 and chain-2 spaces consistent round to round; a loose or tight corner throws off the hexagon's six-sided shape before the solid rows are worked.
  • The invisible decrease in Round 4 works into front loops only; work it loosely so the underarm join doesn't pucker.
  • Because two identical cakes are used for the ombre effect, work both hexagons from the same starting point in each cake so the color shift lines up when the pieces are seamed.
  • Crochet until the piece measures from the back of your neck to your desired sleeve length. The width should be about half your bust size.

Set-up

  • Wind both cakes of YarnArt Flowers so the ombre color progression runs in the same direction on each hexagon.
  • Work a small swatch with the 3mm hook to check that your double crochet tension matches the pattern before committing to Round 1.
  • Measure from the back of your neck to your desired sleeve length, and measure half your bust size, so you know when to stop adding rows in Round 5.
  • Read Round 2 once before starting it: the lacy arch pattern sets the corner spacing that every later solid round will follow.

Finishing

  1. Fasten off after Round 5 on each hexagon and leave a tail long enough for seaming.
  2. Sew sleeve to neckline on each folded hexagon with mattress stitch, then join the two hexagons along the back edge the same way.
  3. Weave in all yarn ends on the wrong side once both seams are closed.

Construction

The hexagon's six corners are set in Round 1 and carried through every later round as chain-2 or chain-3 increase points, so the shape stays six-sided as rows accumulate.

Round 5 turns the piece from working in the round to working flat across three open sides, which is what lets the body extend to any length without adding more corners.

Time per section

Each hexagon, Rounds 1-3about 1.5 hours because the corner-and-side pattern repeats six times per round across three rounds
Sleeve shaping and body extension, Rounds 4-5about 1.5-2 hours because the invisible decreases are fiddly and Round 5 repeats until the body reaches your measured length
Assembly and seamingabout 1 hour because the pattern requires four mattress-stitch seams and weaving in ends on both hexagons

Common questions

How do you know when to stop adding rows in Round 5?
Stop once the piece measures from the back of your neck to your desired sleeve length, with the width at about half your bust size. Check both measurements against your tape before fastening off.
Why is the body worked flat instead of in the round?
Round 5 opens the hexagon along three sides to extend the body, which only works turning back and forth rather than continuing in rounds. This is what allows the body length to be adjusted to fit.
Does the yarn amount matter for the ombre effect?
Yes, the pattern calls for two identical cakes so the color progression matches across both hexagons. Starting each cake from the same point in its color sequence keeps the ombre symmetrical once the pieces are seamed.
