I came across a very creative lady at a blog that took the idea of the shelf and ran with it. You can read about her adventures HERE. I tried using the dimensions she listed and they were a great starting point...but I really wanted mine to match up more to the shelf I already bought. And you may wonder how I managed to build this handy dandy shelf without spending a fortune on wood, saws and sanders? That's simple....FOAM BOARD. I thought it sounded lame and cheap at first. But, really all it was...was cheap! It's much sturdier than you would imagine. I don't think it's so lame. Do you?
The one on the left is mine. Yes, it's not as pretty as the one I bought, and the dimensions are not perfect because I am math challenged, (please don't look too close at that first shelf) but the Foam Board cost me a whole $1.97 and I already had a craft knife and hot glue gun. Now...I have room to fill it up with more Copic Markers. YAY! And if I get too crazy...I can always build another shelf!
