For a easy quilt that looks harder, I'd grab a black for the center square of the block and make a Disappearing 9 Patch. Here's a link to a three color one.

That picture is huge. For a look at the whole quilt, go to 'Pictures', then 'Quilt Gallery', then 'D9P'. It will be there.
There are good tutorials for that pattern here on the QB and on the web in some blogs.
