When I got Ana's book The Handbuilt Home, I was super excited to tackle a project. It just so happened that her mirror plan on page 37 also makes a perfect trophy display. I just replaced the mirror with stenciled cork board so my daughter could display keepsakes along with her trophies and medals.
I followed the plan pretty closely, but I added some cove molding to the center to hold the cork board in place. You can find more details on my blog.
