One of my favorite ways to showcase just about anything and lift its presence in my home is to create a repeated pattern. It is a sure-fire way to elevate the presence of your artwork or collections. I love the examples below.
The fun part about using a repeated pattern is that your object can be anything - I mean anything - and it takes on a life of its own. Postcards, clocks, found objects and even as you see below: Pez dispensers.
Here is my son's artwork in our entryway.
Its not a great photo, but you get the idea.
