Crochet button up cardigan - pineapple pattern
Step-by-step crochet instructions
Step 1
Make a foundation chain of 105 chains or multiples of 10 chains plus 5 additional chains. I count all the chains including the loop on the hook.
Step 2
Increase
Add 10 chains
1st row – [sc9, ch1] to last 13 chs; sc13 plus RC3
2nd row – h4ch, [dc2 on 1ch, ch1, (dc1, ch1, dc1) on 1ch, ch1, dc2 on 1ch, ch1, sk1, (sc1, ch1, sk1) x 3] to last 3 chs; dc2 on 1ch, ch1, (dc1, ch1, dc1) on 1ch, dc2 on 1ch + RC3
3rd row – h4ch, [dc2 on 1ch, ch2, sk3, tr6 on 1ch, ch2, sk3, dc2 on 1ch, ch2, sk2, sc1, ch3, sk1, sc1, ch2] to last 9 chs; dc2 on 1ch, ch2, sk3, tr6 on 1ch, ch2, sk3, dc2 on 1ch + RC3
Step 3
Pineapple pattern increasing chains
4th row – h4ch, [dc2 on 1ch, ch2, sk3, (dc2 on 1ch) x 5, dc1, ch2, sk3, dc2 on 1ch, ch2, sk4, sc1, ch2, sk4] to last 14 chs; dc2 on 1ch, ch2, sk3, (dc2 on 1ch) x 5, dc1, ch2, sk3, dc3 on 1ch + RC3
5th row – h4ch, dc2 on 1ch, [dc2 on 1ch, ch2, sk4, (sc1, ch3, sk1) x 4, sc1, ch2, sk4, dc2 on 1ch, sk5] to last 19chs; dc2 on 1ch, ch2, sk4, (sc1, ch3, sk1) x 4, sc1, ch2, sk4, dc4 on 1ch + RC3
6th row – h4ch, [dc2 on 1ch, ch1, CL1, ch1, dc2 on 1ch, ch2, sk4, (sc1, ch3, sk3) x 3, sc1, ch2, sk4] to last 4chs; dc2 on 1ch, ch1, CL1, ch1, dc2 on 1ch + RC 3
7th row – h4ch, [dc2 on 1ch, ch1, sk2, (dc1, ch1, dc1) on 1ch, ch1, sk2, dc2 on 1ch, ch2, sk4, (sc1, ch3, sk3) x 2, sc1, ch2, sk4] to last 7 chs; dc2 on 1ch, ch1, sk2, (dc1, ch1, dc1) on 1ch, ch1, sk2, dc2 on 1ch + RC3
8th row – h4ch, [dc2 on 1ch, ch2, sk3, tr6 on 1ch, ch2, sk3, dc2 on 1ch, ch2, sk4, sc1, ch3, sk3, sc1, ch2, sk4] to last 9 chs; dc2 on 1ch, ch2, sk3, tr6 on 1ch, ch2, sk3, dc2 on 1ch + RC3
Repeat the pattern starting from 4th row until you crochet 21 rows then join the back and front parts together skipping shoulder parts.
Step 4
Join front and back parts
22nd row – work the pattern for 2 PAs, join 2nd with 6th PA, skipping 3 shoulder PAs. Continue the pattern the regular way for 5 PAs, the connect 10th with 14th PA, skipping 3 shoulder PAs again. Crochet the pattern for the remaining 2 PAs as usual.
Continue the pattern increasing chains for two more rows.
23rd row = 8th row
24th row = h4ch, [dc2 on 1ch, ch2, sk3, (dc2 on 1ch) x 5, dc1, ch2, sk3, dc2 on 1ch, ch2, sk4, sc1, ch2, sk4] to last 14 chs; dc2 on 1ch, ch2, sk3, (dc2 on 1ch) x 5, dc1, ch2, sk3, dc4 on 1ch + RC3
Step 5

Repeat the pattern starting from the 1st round
Step 7
Edges, buttons, and buttonholes
Work sc for all the edges.
Sew buttons making 7 rows intervals between each button or as desired.
Work 9** chains for each buttonhole making 7 rows intervals between each buttonhole as well.
** the number might vary depending on the size of the chosen buttons.
Planning point.
If it is necessary to adjust the crochet project to a different size, plan ahead how many pineapples you need to work to make the width accordingly to your chest circumference.
