Thank you for the reply.
I figured it out, took me a while.
yes. I created a dotted lined rectangle the size I needed, added a pair if scissors, which got cropped in half as I needed it to, to each side in the middle and across from each other. Added my copyright and logo faded out, and saved ads template.
Then I make a working area bigger than my job, create my pattern, then add artboards 8.5x11 that overlap on the margin lines
I zoom in and make sure the scissors meet perfectly, then dupe the main pieces (which are grouped together). When I’m done I simply print Artboards, not full document, and save as pdf so I can make as many as I need.
and voila.
yeah, it’s not as simple as I’d like, but it works.
