AT THE SAME TIME

[LizC]

Hi All

I am currently knitting a cardigan and on shaping have been instructed -
At the same time starting on row 7 of armhole decreases work 2 sts as set, K2tog. join a second ball of yarn, cast off next 17 sts, Ktog, work 2 sts as set. Working both sides at the same time, work rem armhole decs simultaneously. Cast off last sts.[/i][/i]

FYR I have 21 sts on the needle, currently. (with 35 sts at row 7)

I am completely confused on how I do this! Please help..this is a beginners pattern...yek!
