Galoots Assembled,
 
I use a zig-zag folding wooden rule for most of my furniture making.   When 
real precision is needed for layout I use the metal rule off of my 12"  
Starrett and a sharp 4H pencil or an Exacto knife.  I have several old  wooden 
folding rules, but never seem to use them for some reason.
 
Cheers,
John (who is Unpacking and Setting Up his New Shop today!!)
