• ch-sp(s) = chain spaces
• dc = double crochet (this is a UK tr treble crochet)
• rep = repeat
• sc = single crochet (this is a UK dc double crochet)
• slst = slip stitch
• BLO = back loop only

Hexagon Cardigan Crochet Pattern Begins

Body Section (make 2)

Using Color 1, ch5, then slst in first of these 5 ch to form a ring. Alternatively, you can start with a magic ring.

You will now work Round 1 into the ring you have made.

Place a removable stitch marker into the center of the ring so you know where to put your hook for Round 1.

1st round (RS): Ch3 (counts as 1dc throughout) 2dc in ring, ch2, [3dc in ring, ch2] 5 times, then slst in third ch of beginning ch-3., then fasten off. (6 3dc- groups, 6 ch2-sps)

2nd round (RS): Join Color 2 with slst in any ch2-sp, ch3, [2dc, ch2, 3dc] in same ch2-sp, ch1, [3dc, ch2, 3dc, ch1] in each ch2-sp to end, then slst in third ch of beginning ch-3, then fasten off. (12 3dc-groups, 6 ch2-sps, 6ch1-sps)

3rd round (RS): Join Color 3 with slst in any ch2-sp, ch3, [2dc, ch2, 3dc] in same ch2-sp, ch1, [3dc, ch1] in each ch1-sp to next corner ch-sp, *[3dc, ch2, 3dc] in next corner ch-sp, ch1, [3dc, ch1] in each ch1-sp to next corner ch-sp, then slst in third ch of beginning ch-3, then fasten off. (18 3dc- groups, 6 ch2-sps, 12 ch1-sps)

Round 3 is now repeated as follows:

Rounds 4–21 (21, 23, 23, 25, 25): Rep Round 3, in the following color sequence:

4th round (RS): Color 4.

5th round (RS): Color 1.

6th round (RS): Color 5.

7th round (RS): Color 6.

8th round (RS): Color 7.

9th round (RS): Color 1.

10th round (RS): Color 8.

11th round (RS): Color 9.

12th round (RS): Color 10.

Full Color sequence is set by Rounds 1–12.

Rounds 13–21 (21, 23, 23, 25, 25): Rep Round 3, following color sequence as set, ending with 21 (21, 23, 23, 25, 25) 3dc-groups along each side.

Fasten off, then weave in ends on wrong side.

Folding Your Crochet Hexagon Cardigan

• Number each corner of your hexagon in order, from 1 to 6 around in a clockwise direction, because this will help with folding.
• Fold corner 1 to meet corner 2, fold corner 4 to meet corner 5, then fold corner 3 to meet corner 6.
• This will create an L-shaped piece for each half of the body.

• Fold the hexagon, as in the diagram above, to make an “L” shape.

• Next, sew along one of the long edges to create the shoulder/sleeve seam, using whip stitch, because this will create a flat seam. Make sure you sew through the back loops of the stitches.

• If you place each piece side-by-side, you will see the arms and body taking shape.
• Continue both sides alike following the instructions to lengthen and widen the body.
• Repeat for the other piece, mirroring the seam.

Body Lengthening And Widening

Keeping color sequence correct, and with right side facing, join next color yarn in any ch-sp in line with side seam. You will now work around only three sides of the piece.

Round 1 (RS): Ch3, 2dc in same ch-sp, 3dc in each ch-sp around, then slst in third ch of beginning ch-3, then fasten off.

Rounds 2–4 (6, 6, 8, 8, 12): Rep Round 1 a further 3 (5, 5, 7, 7, 11) times, maintaining color sequence.

You’ll have 25 (27, 29, 31, 33, 37) rounds on both front and back.

Centre Back Widening

On left piece, place a stitch marker in ch-sp in line with shoulder seam, then join next color to opposite end of center back seam, in opposite corner ch-sp to marker. (24 (26, 28, 30, 32, 36) ch1-sps between markers)

Row 1 (RS): Ch3, 1dc in same corner sp, ch1, [3dc, ch1] in each ch-sp to marked sp, 2dc in marked sp.

Fasten off, but not turn work.

Row 2 (RS): Join next color to top of beginning ch-3 of previous row, ch4 (counts a 1dc, ch1), [3dc, ch1] in first ch-sp, [3dc, ch1] in each ch-sp to last 2 dc, skip 1 dc, 1dc in last dc.

Fasten off, but do not turn work.

Row 3 (RS): Join next color to third ch of beginning ch-4 of previous row. Ch3, 1dc in same st, ch1, skip first ch-sp and first 3dc-group, [3dc, ch1] in each ch-sp to last ch-sp, skip last ch-sp, 2dc in last dc.

Fasten off, but do not turn work.

Row 4 (RS): Rep Row 2.

Rep Center Back Widening on second piece then join center back seam with whip stitch

Edging Your Crochet Hexagon Cardigan

Using next color in sequence, and with right side facing, join Color 1 with slst in bottom corner stitch of left front.

It is not necessary to count your stitches for the edging rounds. If you place stitches as instructed, your edging will sit nice and flat.

Foundation round (RS): Ch1 (does not count as a st), then work [2sc, ch2, 2sc] in same st, 1sc in each dc to opposite end of hem (skipping the ch1-sps), work [2sc, ch2, 2sc] in corner ch2-sp. Now work along front edges and neck, as follows: 1sc in each dc and 1sc in each ch1-sp to row-ends of center back, work 2sc in each of the first 4 row-ends, 1sc in center back joining seam, then 2sc in each of the next 4 row-ends, then continue as before with 1sc in each dc and 1sc in each ch1-sp to end, slst in first sc to join, slst in next sc and slst in corner ch2-sp.

Next round (RS): Ch3 (counts as 1dc), 2dc in same corner sp, 1dcBLO in each st to next corner sp, 3dc in corner sp, 1dcBLO in each st to end, then slst in top of beginning ch-3 to join, invisible fasten off.

Next round (RS): Join next color in sequence to BLO of center dc of corner stitches. Ch3 (counts as 1dc), 2dc in BLO of same st, 1dcBLO in each st to next corner st, 3dc BLO in corner st, 1dcBLO in each st to end, then slst in top of beginning ch-3 to join, invisible fasten off.

If desired, you could create a deeper edging, by repeating the last round as many times as required.

Weave in ends on wrong side.

Sleeves

Round 1 (RS): Join next color yarn to any ch sp, ch3 (counts as 1dc), 2dc in same ch-sp, ch1, [3dc, ch1] in each ch-sp around and in join of shoulder seam, then slst in third ch of beginning ch-3. (22 (22, 24, 24, 26, 26) 3dc-groups and ch1-sps)

Fasten off with invisible fasten off.
