Thanks everyone, I have started using Anne Wiens "Thrifty Quilter" method 2 years ago to cut my leftover fabric into squares, so it's pretty easy when you have all the scraps already cut and just have to rummage around in your bin to find matching pieces. I have to make a quilt for my friend's baby, she liked this one, so I'll make her one out of my 3.5" squares next.
