Oh thank you so much. That makes a lot more sense!
Also, I am having trouble with the buttonholes as well- I think I put them in Row 3 and then every 8 rows. Is that right? Also, regarding the buttonholes, do I just make them myself, or is that what the YO, K2TOG in row 3 is doing?
I'm sorry! This is the first sweater I've ever made!
Row 3 (buttonhole row): K2, yo, k2tog, rib to last 4 sts, k4.
