Adding the coloured circles to Dolly background

This panel shows the small coloured circles I have been working on over the past few nights. They are in yellow, red, blue and green (to be worked). These are the colours that most DNA sequencing programmes use so I wonder if that was Andrew Crummy's inspiration. There are also four bases in the DNA molecule which are often depicted in these colours. Lots of possibilities anyway. Circles are also a motif used to represent all sorts of biological structures e.g. nucleus, cell, egg...the list goes on. I decided to work the circles in woven spider webs to give a nice, raised profile and a clear, circular shape. To work them, the number of 'spokes' (stitched from outer rim of circle to centre) must give an uneven number of segments or else the weaving doesn't work and is wavy. These small ones have nine spokes and each takes an entire length of wool to complete.
