Here is the pattern for crochet blouse, which I made for my mother.
I use 5 skeins of Nurture by Euro Baby yarn in pearl grey color and crochet hook 4 mm.
Steps
Ch 100 (or any multiple of 20) join with sl st in back bump of first ch making sure there are no twists in ch.
Rnd 1: Ch 1, working into back bumps, sc in same ch as join and into each ch around; join with sl st in first sc. [100 sts]
Rnd 2: Ch 2 (does not count as st, now and throughout pattern), (3 dc, ch 2) twice in same st as join (first corner made), *[sk next 4 sts, (3 dc, ch 2) in next st] 4 times; sk next 4 sts**, (3 dc, ch 2) twice in next st; rep from * around ending last rep at **; join with sl st in first dc. [72 dc and 24 ch-2 sps]
Rnd 3: Sl st into next 2 sts and into ch-2 sp, ch 2, [3 dc, ch 2,] twice in same ch-2 sp, *[3 dc, ch 2] in next ch-2 sp and into each sp up to corner ch-2 sp**; [3 dc, ch 2] twice in next corner ch-2 sp; rep from * around ending last rep at **; join with sl st in first dc. [84 dc and 28 ch-2 sps]
Rnds 4-32: Rep Rnd 3 until you have reached a desired length.
Rnd 33: Ch 1, sc in same st as join and into next 2 sts, *3 sc in corner ch-2 sp, [sc in next 3 sts, 2 sc in ch-2 sp] rep up to corner; then rep from * around; join with sl st in first sc. [724 sc] Fasten Off.
Block to dimensions below. To block, simply wet the poncho down and stretch it out over a blocking mat, a big blanket, or even a few towels. Pin the edges in place with rust-proof pins and allow to dry completely.
If you need it longer, you can always continue to do more rounds until it's the desired length.
