A bit slow in getting to this point, but nonetheless a flimsy has emerged.
This is what it looked like after adding colour. As the piece had a fair amount of colour already I added the white with black and white circles, and trying to make it a bit bigger and less square, added the two yellow strips.
Next, Serendipity.. hmmm... using the floor to see this layout, and I think it will work, two different purple pieces, the 4.5" green made squares and the 3.5" mauve strips interspersed with some on the yellow and turquoise bits. A liked it more at this point before putting the bits together.
