I saw this tutorial/idea at a blog party recently and lost it but since Google is awesome I found it again.
Anyways, I thought I'd give it a try.
I measured the length & width (excluding the little groove on the inside). Measured & cut the scrapbook paper into the right size to fit and be *almost* even on placement.
Really, that's it. It was very simple.
Sure, Anthropologie's looks better but mine cost around $150 bucks less. ;)
