Neville tried 3 layers of 2mm all one colour with the corners all skew. The plan was to make a circle but there were little bumps all around.
The dichro buttons had the corners ground off one set and the other three were just squares set square.
The little earrings had 3mm cover set skew. They did not turn out circular.
The black blob was a white base with 4 little black squares with a narrow space between them and a clear top. The black squares just melded together.
We plan to test the earrings with the 3mm top square on and the dichro ones as squares placed squarely and the top a bit bigger than the dichro base.
