Oooooh . . . This could be a trouble spot. I can say from my 8x10 holders that half will accept paper, and others will not. On the holders that won't, the trough on each side rail is too narrow for normal double-weight paper. Film slides in just fine. You may want to ask the forum in advance if a particular make and model of holder will accept a certain thickness of paper. It could save you the heartache of ordering a holder that won't work with certain papers.
