I'm knitting a child's cardigan and it calls for two bands down the front. I've knit the first band and placed pins for where the buttons will be placed. Now I need to do the second band (where the buttonholes will go). How do I do the buttonholes (the pattern says to k2 together, yo), and since the band is only one inch (which is 4 rows), on which row do I begin the buttonhole? I'm totally confused since I've never done this before . . .
