Corner to Corner stitch (shell stitch)

I came across this link from one of the crocheting groups I am a member of, and I loved the look of it, so I have decided to have a go at it and see where it will take me.

I have a ball of white yarn, sitting near my keyboard where I have been crocheting up some granny squares whilst I watch videos on Youtube.com. So I grabbed it and have already completed 6 rows! It is so easy to do, I am going to continue for a few more rows and then I might do a colour change. But I will have to have a look at my stash and see what colour yarn to use. I dont know if I will make an afghan out of it, or a winters shawl. I guess it will have to depend on how far along I get before I get tired of the pattern. (O.o) Or how many projects I start from now till I decide it is finished.
