I do both at the same time. I print both sheets, with top side mirrored, 
line them up together by eye using a bright light to see through, and 
staple a few times along one edge. Then I slide the cleaned copper board 
in between them and use a clothes iron to bring it up to temp, followed 
by a laminator several times. Biggest board so far is 4 inches by 8 
inches. Same process works for single side with component outline.
