I bought some fleece for the backing for the One Block Wonder. I was looking for periwinkle as Wynn Anne suggested, but there was none to be found, so I went with a soft spring green. I think it will look very nice. It's a very light fleece, so this one will be for the summer months, or winter in warmer climes.
I also decided on my next project to make.... it's very simple, I wish I could say I thought of it myself, but alas it's a free pattern and was available on the Timeless Treasures site. Its called Jungle Rain and if you're interested I've shared it. I had downloaded it earlier and saved it, it's in my google docs so I can share.
