Help with shape raglam armholes please

Hi, can someone please help me with this instruction. This is the first time i’m knitting a cardigan and I’m already lost with shaping the raglam armholes. I have no idea what to do here.

Keeping patt correct, cast off 2(2-3-4-4) sts at beg of next 2 rows … 94(102-108-118-126) sts.
Dec one st at each end of next 3 rows.
Work 1 row patt.
Rep last 4 rows 4(6-6-8-11)times … 64(60-66-58-54) sts.
Next row - Patt 2tog, patt to last 2 sts, patt 2tog.
Next row - Patt to end.
Rep last 2 rows 12(9-11-6-3) times … 38(40-42-44-46) sts.

You’ll want to decrease at each side of the knitting and maintain the pattern you have been doing as best as you can. You’ll be losing sts at each side, so you may have to give up the pattern at the edges so that you can keep decreasing.
row 1 cast off 2sts
row2 cast off 2sts.
row 3 decrease 1st at the beginning and end of row
row 4 decrease 1st at the beginning and end of row
row 5 decrease 1st at the beginning and end of row
row 6 work across this row with no inc or dec
repeat rows 3-6 for 4(6-6-8-11)times … 64(60-66-58-54) sts.
Next row - Patt 2tog, patt to last 2 sts, patt 2tog.
Next row - Patt to end.
Rep last 2 rows 12(9-11-6-3) times … 38(40-42-44-46) sts.

Thank you so much! :muah:
