The foundation for your 3D Your Names masterpiece is simply writing out your word or words on the paper and getting them to fit the space well first. Your letters should be evenly spaced out and not crowding each other too much.
Now, expand your line letters into block style letters. It may help to draw a guide line across the top and bottom of the letters to keep you an track. In my case I built the block letters centered around the line letter like on the "A" if possible. For other letters such as the "N" and the "J," I built the block letter off to the right of the line letter. Just work your way through the letters doing your best to even out the spacing.
