How would one laminate a large (approx. 24 x 32 inch) poster? I want to create some wall art for my boring room and was inspired by a bunch of magazines, which I proceeded to chop up. My plan was to replicate/interpret a cool photograph into a large poster using blocks of colors cut from said magazines which would then be glued onto butcher paper.
But I want the finished poster to be durable and able to be rolled up/stored without having to worry about all the little magazine bits falling off, and I don't think a sealer like Modge Podge would be flexible enough. I remember in elementary school they seemed to have a way of laminating everything between two sheets of plastic... Any ideas, anyone? Any help would be greatly appreciated!
