I'm learning that a person can turn layers in a pdf pattern on and off in Adobe Reader.
You can print only one layer (just the size you need) if you want instead of the entire nested pattern.
Is there another program that I would have to export my printed pages to (from PatternMaker) in order to bring them into Reader and use this function?

I found that Adobe Illustrator works for this.
Bring a pdf page into the program. Draw over the lines designating the sizes, each size on a different layer. Group them and when you open the pdf in Reader, choose layers and turn them off and on at will.
