It's for a scarf, and basically the effect is sort of giant, loose normal knitting stitches. it's quite a thick yarn on size 10 needles if that helps. I'm pretty much a beginner, it looks just like your normal knit purl, but you have to do something to make the stiches giant but I can't work it out 
" alt K1, P1; work 1 yarn over before each stick. (What does this mean??) On all following rows work sts as they appear and a yarn-over before each stitch, let the yarn-overs of previous row slide off the needle" (don't get that last bit either?)
Thanks if someone can help me understand.
