Pattern Notes

For this hexagon cardigan pattern, 3trr-groups with ch1-sps are used throughout, therefore creating a hexagon that doesn’t sit flat. This shape is required in order to achieve an L-shaped piece for each half of the cardigan.

Abbreviations

• BLO = back loop only
• ch(s) = chain(s)
• ch-sp(s) = chain spaces
• dc = double crochet
• dc2tog = double crochet 2 sts together (to decrease 1 st)
• rep = repeat
• slst = slip stitch
• tr = treble crochet

Granny Hexagon Cardigan Pattern Begins

Body Section (make 2)

Using Colour 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 1tr throughout) 2tr in ring, ch2, [3tr in ring, ch2] 5 times, then slst in third ch of beginning ch-3, then fasten off. (6 3tr-groups, 6 ch2-sps)

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

3rd round (RS): Join Colour 3 with slst in any ch2-sp, ch3, [2tr, ch2, 3tr] in same ch2-sp, ch1, [3tr, ch1] in each ch1-sp to next corner ch-sp, *[3tr, ch2, 3tr] in next corner ch-sp, ch1, [3tr, ch1] in each ch1-sp to next corner ch-sp, then slst in third ch of beginning ch-3, then fasten off. (18 3tr-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 colour sequence:

4th round (RS): Colour 4.

5th round (RS): Colour 1.

6th round (RS): Colour 5.

7th round (RS): Colour 6.

8th round (RS): Colour 7.

9th round (RS): Colour 1.

10th round (RS): Colour 8.

11th round (RS): Colour 9.

12th round (RS): Colour 10.

Full Colour sequence is set by Rounds 1–12.

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

Fasten off, then weave in ends on wrong side.

Folding Your Granny 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 colour sequence correct, and with right side facing, join next colour yarn in any ch-sp in line with side seam. You will now work around only three sides of the piece. These three sides are the bottom hem, the front edge and centre back edge - I have indicated these in the diagram below, so you can see where to work.

Round 1 (RS): Ch3, 2tr in same ch-sp, ch1, [3tr, ch1] 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 colour 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 colour to opposite end of centre back seam, in opposite corner ch-sp to marker. (24 (26, 28, 30, 32, 36) ch1-sps between markers)

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

Fasten off, but do not turn work.

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

Fasten off, but do not turn work.

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

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 Granny Crochet Hexagon Cardigan

Using next colour in sequence, and with right side facing, join Colour 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 [2dc, ch2, 2dc] in same st, 1dc in each tr to opposite end of hem (skipping the ch1-sps), work [2dc, ch2, 2dc] in corner ch2-sp. Now work along front edges and neck, as follows: 1dc in each tr and 1dc in each ch1-sp to row-ends of centre back, work 2dc in each of the first 4 row-ends, 1dc in centre back joining seam, then 2dc in each of the next 4 row-ends, then continue as before with 1dc in each tr and 1dc in each ch1-sp to end, slst in first dc to join, slst in next dc then slst in corner ch2-sp.

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

Next round (RS): Join next colour in sequence to BLO of center tr of corner stitches. Ch3 (counts as 1tr), 2tr in BLO of same st, 1trBLO in each st to next corner st, 3trBLO in corner st, 1trBLO in each st to end, then slst in top of beginning ch-3 to join, 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 colour yarn to any ch-sp, ch3 (counts as 1tr), 2tr in same ch-sp, ch1, [3tr, ch1] in each ch-sp around and in join of shoulder seam, then slst in third ch of beginning ch-3. Fasten off. (22 (22, 24, 24, 26, 26) 3tr-groups and ch1-sps)

Rounds 2–17: Maintaining colour sequence, rep Round 1.

NOTE: Sleeves can be lengthened or shortened by working more or fewer rows here.

Weave in ends on wrong side.

Sleeve Cuffs

• Foundation round (RS): Join Colour 1 to any ch-sp, ch3 (counts as 1tr), work 1dc in each tr (skipping the ch1-sps), then slst in third ch of beginning ch-3. 66 (66, 72, 72, 78, 78) sts.
• Next round (decrease round): Ch1 (does not count as a st), 1dc in first st, dc2tog, (1dc in next st, dc2tog) to end, then slst in first dc. 44 (44, 48, 48, 52, 52) sts.

Sleeve Ribbing

• Row 1 (RS): Ch15, 1dc in second ch from hook, 1dc in each ch to end, slst in next st of decrease round, slst in following st of decrease round, turn. (14 dc)
• Row 2 (WS): Skip last 2 slsts, 1dcBLO in each st to last st, 1dc in last st, turn.
• Row 3 (RS): Ch1 (does not count as a st), 1dc in first st, 1dcBLO in next 13 sts, slst in next st of decrease round, slst in following st of decrease round.

• Fasten off.
