Shiny, hmm... first thought for something completely different was shisha. I dug out some very authentic (rough!) old shisha mirrors and thought about stitching them in spring colours.
Just in time I remembered - I did this for C&G and once is MORE than enough.
But sticking with the mirror idea I found some very shiny silver card and quickly zigzagged it in crocus-inspired colours. OK it's not one of my most memorable efforts, but I did save myself many hours of torture by swerving the shisha stitch :-)
The only pain then was trying to get a photo without reflections!
