black fabric challenge

well, have signed up to do city and guilds level 3 certificate in design , patchwork and quilting with school of stitched textiles
they have  a  competition on their facebook page for a piece made with predominantly black fabrics
REALLY tough
with my poor eyes, and my bedroom ( ahem  studio ) poor lighting, black on black a real problem
quite like the ( unintentional) effect on my backing of the free motion, bit cobwebby.
