I chose a layer cake of Hello Luscious by Basic Grey, but stuck to the pinks and blues, since she told me recently that she doesn't like green. Unfortunately her favourite colour is now purple, not pink like I think it was at the time I bought the layer cake. I am pretty sure she will still like this though. I may just add in some purple anyway, I have a few ideas.
Anyhow, the centre is done, and it was supremely fast, since no cutting was required and there are just 28 squares. The most time consuming part was getting it to look 'random', but in a way that pleased me. I spent far too long on it and in the end just started sewing so I'd stop changing my mind!
I had different plans to begin with, but on laying out all the squares I decided that they didn't need to be cut up, they were just fine as big, bold patches. Now, borders and perhaps a bit of applique, and then another quilt top will be done. Just need to choose and then buy some border fabric.
