New!!! Idea- Clear vinyl is a great way to transfer drawings.
  I purchase clear vinyl from Wal-Mart and it is priced at $2.57 per yd. Four yards is enough to start with.  It is called Double Polished Clear Vinyl and it is made by Kittrich Corp.. The material is fairly thick and holds it shape well, which is great for making Templates. 

	Here is an example of a template I made to transfer the M-drawings for the temporary firewall.  I used a fine point Sharpie to transfer the drawing. After transferring the drawing simply cut out the pattern and its ready to use.

	One Concern I have is if the vinyl is placed in a heated space such as window.  The material could  get out of shape. I suggest  checking  the pattern against the M-Drawing  before use.
