Synchronized Squares Quilt Along at P.S. I Quilt

I'm joining yet another quilt along. I missed Rachel's Pinwheel Quilt Along  and the Postage Stamp one, but third times the charm.
I am using my Fig and Plum Layer Cake. I've been sitting on it and had assigned it to another project, but I think the raw edges will look 'cute' with the florals. I don't have my solid colour picked out yet. I am not using a pre-cut for the solid background so I will have more flexibility with colours.Any suggestions?
Rachel gives very detailed instructions so I suggest joining in. There are some cool fabrics being chosen so the resulting quilts should be awesome.
