Mini Bookshelves of My Dreams

I have a bit of an obsession with book display units.  I hate to admit that I have probably spent over 24 hours researching different types of book units on the web.  I am particularly drawn to wall mounted structures that save floor space for play or other endeavors.  For a long time and still today, I have fantasized about the rain gutter book shelves.

About a week ago though, I stumbled upon a new-to-me blog called "The Sweet Survival" and finally found what I considered to be the holy grail of cool wall mounted book shelves.  Feast your eyes on these lovelies..

I then spent another two days trying to find someone on the web that made them and sold them since I am not exactly a carpenter.  No such luck but dang it would be a great idea for those etsy-minded folk out there!  I finally decided that I wanted that look enough that I was willing to throw my dice on the table and headed to the closest home improvement warehouse.
 
I thought I would run into trouble since I don't own a table saw.  However, a super helpful lumber man went ahead and cut nearly all my pieces for me at the store.  All I had to end up cutting were the little stick pieces on the sides of each shelf.  I ended up changing the dimensions a bit of my mini bookshelves, primarily to save the before mentioned helpful lumber man from cutting wood all day.  I would say though that if I could do one thing over again with the project, I would have chosen a nicer wood.  Mine is some type of particle board which gave me occasional issues when small particles wriggled loose and fell out of my boards!  Good thing I had wood filler.

Anyway, all I really had to do was sand the pieces, nail the three main sides together, saw and add the stick pieces.  From there, I painted it and then used a satin varnish to add more protection to the unit.  Lastly, I secured it to the studs in the wall and added the vinyl numbers.  Thanks so much to "The Sweet Survival" for the great idea and DIY directions.  For the steps and awesome other inspiring stuff on that blog, please go to http://thesweetsurvival.blogspot.com

While mine doesn't seem as perfect as the one on The Sweet Survival, I am content that I got the look I was going for.  What do you think?
