Help on knitting a blanket . . .?

I am kntting a blanket (with squares obviously). Here are some details about my materials: three skeins of Angel Hair yarn (120 yards long each), and size 10 knitting needles. I can buy more yarn if necessary. I have only knitted like once before, and I can't remember at all how to. Please don't question me starting off with a blanket rather than a simple scarf. What I need is instructions on how to make the blanket (maybe websites) and pictures. Thanks!
