Check out the rulers that the American Printing House for the blind has at
as one of them does have markings for 1/8-inch measurements. Most of us learn that 1/16 inch is exactly half way between the 1/8-inch markings and ca
do pretty well without having a specific 1/16-inch marking. For example, half way between the 3/8-inch point and the 1/2-inch point is 7/16. To some
degree, this is actually easier than trying to count 1/16-inch lines. I believe that some of the metal tape rulers have either 1/16 markings on the first few
inches or have a short ruler attached with such markings.
Could you explain what a perpetual calendar is?

to emboss it, it got all garbled and unusable. Although I am sure it could be sorted out, it would be very time-consuming. We are hoping that someone
knows where we can purchase one.
