As a rule of thumb, I like to tell people to use any shape and size, but keep them all one color. There might be some exceptions to the rule (i.e.; different finishes, but all antiques, etc.,) but it is a safe rule to follow. And it is always smart to take the time to make templates and lay them out first before you start nailing away. Also, make sure to take into account the whole space. If you are clustering the pictures on one wall, find the center of the wall from the sides, then start the center of your cluster 2/3 the way up the wall and work your way out. If you are clustering above a piece of furniture (sofa, hall chest, piano etc.) then you still want to stay roughly around 2/3 the way up the wall, but the bottom of your cluster should not be higher than 18" above your piece of furniture - no matter how high your walls are.
