The C,D & E Add additional releifs around the outside.
The C uses two bitmaps One for the background that the letter sits on and a weave pattern bitmap around the perimeter.
The bit maps I'm using are from Dan Sawatzky's Texture magic collection.
I should also mention that these letters are all done Using High Density Urethane Sign Foam, Then the Majority of the finishes are from the Modern Masters line of metalic paints.
Only 21 more to Go u-all come back now ya here.
