To the Editor:
I would appreciate it if someone
could help me find a more convenient
ruler for use with house plans.
I'd like a flat ruler that has just one
scale, 1/4 inch equals 1 foot, on both
sides. I have not been able to find
such a ruler.
My present ruler does have the 1/4-
inch scale, but my problem is that it
also has five other scales, one on each
side of each of its three edges. Every
time I pick it up, I have to find the
correct scale before I can use it.
While working over drawings, I probably
set my ruler down, and then pick
it up again, 20
