I have done a QAYG baby quilt Log cabin style starting with 2 3.5" squares and my serger. I used a bunch of ugly fabric (and in this case ugly + ugly = uglier). It's about 42" square. What I have found is that the seams have pulled apart--careful stitching is essential. I use it in the bottom of the pack n play for when the grands need a place to sleep. And I haven't made another since.
