Story Boards are a perfect way to seamless display complimentary images from a session. A clean collage of images also allows you to not be forced to choose between which ones to print! Below is an example of a 10×20, 3 image story board. This size is a great option, as is 20×20 which can accommodate more photos!
All of my wall prints, size 11×14 and up, are printed on the styrene mounting. This is done both for appearance, stability and longevity. Styrene mounting sets my wall prints apart from my gift prints (8×10 and below).
While they can be framed, they are durable enough to be propped on a shelf or displayed on a miniature easel.
