The sweaters of the triplets are crocheted in back and forth rows.
The sweater is crocheted in multiple parts, see image.
Part 1
Ch 11 with blue/green/pink.
1. 1 sc in each ch from the 2nd ch from the hook (= 10 sc)
2. - 9. 10 sc, ch 1 at the end of each row and turn.
Part 2
1. 2 sc, ch 4 (leave the rest of the st unworked)
2. 1 sc in each st from the 2nd sc from the hook (= 5 sc)
3. - 9. 5 sc, ch 1 at the end of each row and turn.
Fasten off. Now attach the yarn to the last st of row 9 of part 1.
From here, you crochet part 3.
1. 2 sc, ch 4
2. 1 sc in each st from the 2nd sc from the hook (= 5 sc)
3. - 9. 5 sc, ch 1 at the end of each row and turn.
Fasten off.
Now you will crochet the sleeves (part 4 and 5) along the sides.
Attach the yarn again at the level of row 4 of part 1.
1. Make 10 sc along the side (1 sc in each end of a row)
2. - 4. 10 sc
Repeat this on the other side of part 1 for the other sleeve. Fold your work in half and sew the sides of your sweater closed according to the instructions in the image. You can now put the sweater on and sew the back closed.
