This is the U finished, along with a couple of leftovers from my last project. The one on the far right has had its height adjusted to whatever it was I was finishing letters off to. Pity the poor brain, it can't even think back that far.
Here is my C and a friend. C is made the exact same way as the U (just tilt your head to the right and you'll see it). I prefer a square-ish shape to start out my C's, rather than the rectangle for the U, but that' s personal preference.
