I used an old school overhead projector and a transparency slide to do my profile. This was great because it was easy to draw in doors and such and see the actual size. Then I could take measurements and know if I liked how large/small the features were.
Here's what I did:
1. Put an 8 foot piece of tape horizontally on living room wall.
a. The 8ft piece of tape represented the trailer length.
2. Draw your profile on a transparency slide while it is one the projector.
a. Kinko’s (FedEx) will sell you one or two blank transparency slides or you can get them from an office supply store.
3. Pulled the overhead back away from the wall until the base of the profile covers the 8 ft piece of tape or whatever the length of your trailer is.
4. Draw in your doors, windows, side tables, and such on the transparency
a. This will help with placement of everything).
5. Once everything is as you want it, take a large piece of white cheerleader break-through paper (craft store) or a white canvas or large piece of cardboard and tack or tape it to the wall where the image is projected.
6. Draw the frame and projected profile image onto the paper or material.
7. Use scissor to cut out the drawn image.
8. Now you have a template that can be used several times.
I ended up adding a 1-foot extension to my first tear because my profile was taller than normal.
