I have wanted to try these book shelves out for a while but never really found the time. A couple months ago I even made an attempt to get the supplies from Lowe's, but I struggled to find what I needed. Attempt never two went a lot better. I started with doing only two shelves and can add more later if I decide.
There are a million tutorials for how to accomplish this, but this is the one I used.
I had quite the difficult time putting this together today. It seemed like one thing after another. I even have a few wounds from "shrapnel" while cutting the gutter.
Advice: mount your corner piece first making sure that the screws are no where near the part the gutter attaches to. Also, drill slowly! I learned this the hard way.
