Just a little something for the Magic players in the audience - I designed a net for a really nice (IMO) spindown D20. Each number is aligned so that the number above is literally above and the number below is literally below it. The faces are also shaded to indicate how the numbers flow into each other.
Here's how the finished die looks:
And here's the net. If you make one, I'd love to see - tweet a photo to @LaurieCheers!
