There's 1001 ways of printing, but I do all my printing and resizing from XNview, just one of the many free image viewers out there. Although it's not something others don't do, it will show you the page before printing so you have an idea what size the print out will be.
(I also set my printer to only use black ink for the pattern to save on ink - unless it's one of Ray's red outline patterns, of course.
I think the 5/8 hole for the thumb may be too small. I have small hands and when I made one of these, I drilled the hole 1" and it was tight.
