Use wrapping or packing paper to visualize your design when choosing the arrangement. Cut templates from the paper that match the size of each frame. Mark on the paper where the hanging nails will be located and tape the templates to the wall in an arrangement you like. If you don't like how they look, no problem, simply move the templates until you do. Moving just the templates and not the pictures will prevent you from making unnecessary holes. Be sure to use "blue tape" that will easily peel off and will not leave a sticky residue on your walls. Once you find the ideal arrangement for your pictures, simply mark your nail holes into the wall using the corresponding nail marks on each template, remove the template and now you are ready to hang the pictures. It's as easy as that!
