Wow, those are amazing. I rather like the set at the end, the same set of blocks done with all the different stitching n stuff - really neat how they all look so different from each other.
I don't know if I've the precision to do proper quilting :). I've tried a little, though, just making some simple pinwheels out of silk - very pretty colours. Might turn that into a cushion one day if I ever haul it out of the sewing stash :).
