Still not quite finished but the patchwork part has now been hand- quilted (can you hear my fingers screaming?).
After all your great suggestions I went for a very simple approach by stitching alternate squares just inside the seam line.
It's a bit puckered in places but on the whole I'm quite pleased with it.
I managed not to photograph the border - doh - but it's made of the cloud fabric and after a consultation with my design guru I've decided to quilt it by stitching round every third (or so) cloud.
Then it's just a matter of binding and hey presto - done!
Not sure when! I'd like it done by tomorrow so I can start my next one!!!
