How To: Draw the letter "G" as a block 3D letter

The instructor in this video is showing viewers how to make a Block G in 3D. The process involves drawing the initial capital G. Then a line is made as an outline around the top of the letter and another line is made the same way at the bottom of the letter, so it appears to have a G made with 3 lines. Then the whole G is colored in to make a solid block letter. At the top of the G, a parallel line is drawn and filled in to appear the top is 3D. Another parallel line is drawn at the bottom in the same fashion. This is repeated at the middle part of the G where the lines cross in a T fashion. When these are finished and colored in, the G appears not only blocked but also in 3D!
