Just wanted to let you know I used these two tutorials and it was fun to make smaller design boards. I made a 14 x 15 and 16 x 20 from a 20 x 30 foam board. They took about three hours to complete. I would suggest you make sure you have plenty of glue sticks before you start. I used about 8 regular size sticks for these two boards.
Here's a picture of my 16 x 20 board.
