I've read this so many times now that it has become mush in my head. Could someone please set this up for me so I can continue with this sweater!?

"begin binding off for shoulder at left edge on every alt row 8 sts once, 6 sts twice and 3 sts 3 times. I know if I just walk away for a few days it will all make sence but I can't!
Thank you for your help in advance.
