My only A3 print will be the set of images on the left and I will be mounting them on a foam board, and then on top of that I will be adding cut-outs of from the other set of A5 images (Right). I originally wanted to gather up some leaves and small computer parts to stick onto my A3 Print but after realizing I would not have time to gather all of the parts needed, I decided to change my idea. I will instead mount the A5 pictures on foam board to make them stand out on top of the image.
My framing idea for these two sets is to either have them side by side as above, or vertical, with the tractor being above the ground. I will have a large piece of card as a background, with two smaller foam boards holding each set within the larger piece.
