Well, I finally got all of the parts cut out from MDF back. But there was problem, the windows and doors did not fit the openings, they were too small.
I started by using my new Dremel 4000 to sand the openings, my first time using one EVER, got carried away with the power and made a couple of the openings too large. I will have to fix that later with trim.
Then moved on to the side walk and found out that it needed about an inch and a half cut off one side and 1/2 inch on the front to fit around the bakery. So I had to call my DAD to figure out how to change the tools, Duh! I did manage to cut the side walk but very unconventionally, (too embarrassed to explain).
Then I used a grout saw to cut the channel lines in the MDF sidewalk by hand. This tip came from about.com
I read an article about Bromley Stencils and that you could use regular sanded grout instead of the brick compound they sell, also from about.com. Well I tried it, it does work but maybe not as convenient as the brick compound. The cost of the grout was definitely cheaper and you get more for less money and it comes in more colors, I got Quarry Red. I did not enjoy the mess of mixing the grout with water and the protective wear required to mix the stuff. So far the consistency is about the same but did not spread as easily as the brick compound but it appears to be drying about the same time. I am still undecided. But I have decided that I need a extra large brick stencil for this project!!
