Feed the newbie

Hi all. I just wanted to make a quick introduction. I found this site while looking for a picture of a ripple afghan to post to my blog. No, I didn't steal anyone's work. I didn't think it was right when I found all of you.

I'm currently working on a black and grey ripple for my hubby. He loves it, but boy am I ready to move on to something with some more color! I'd post a pic, but my camera is currently on the fritz. I'm going to try and borrow one from someone. He'd like me to make the edges straight by somehow creating triangles of stitching to put in the valleys of the ripple. Anyone got any advice on this or any pictures they can lead me to?

Thanks for letting me join in. I look forward to hearing from anyone with advice!
