With Right Side facing, pick up and knit (huh..?? where on earth do i pick up them, and where do they go..?) approximately 76 stitchess evenly around upper back edge.(erm... upper back edge of the back or of the sleeve..?) Bind off stitcheds purlwise. (erm..? purlwise bind off..? [that will be on knittinghelp.com yeah..?)
Picking up stitches means taking the edge of your piece, inserting a needle and `making' a knit stitch - repeat for 76 stitches along the upper back (that will be the part you don't use for the sleeves) and 76 along the upper back. It will be easier if you seam the sleeves up first, then you'll only have to worry about the upper and lower back edges. Then you bind off in purl stitch, and yes, knittinghelp.com should explain how to do that along with how to pick up stitches.
