DIY (if you dare!) Project: Customizing a Bookcase

I have loved the idea of customizing a bookcase by wallpapering the backs of the bookcase with pretty paper or fabric. Honestly, though, I don't have the time or inclination right now to deal with glue and lining things up properly. We need shelving in the baby room, though, and I wanted to do something besides putting another utilitarian bookcase up in another room. So I thought a coat of paint would just be the perfect way to perk up a standard bookcase. I bought a quart of semi-gloss paint and an Ikea Billy bookcase and went to work.
Here's a before pic of the bookcase from the Ikea website:It's okay, but blah...just a regular old bookcase. I painted the back of the bookcase with a gorgeous aqua color (Olympic Premium in Caruso), and here is the result:

I will say that this project did come with a slight snafu. I had perused the Internet and found instructions on Domino that confirmed what I wanted to do: prime the back piece, then paint it. I primed the white laminated side of the backboard (the side that would normally show), and immediately had an idea that it wasn't going to work out because the primer was beading and not really sticking to the laminate. I painted two coats of primer (exactly the kind Domino had mentioned) and two coats of paint and it did in fact cover just fine. I let it dry overnight and when I went to put it into the Ikea bookcase...

Disaster.

Utter disaster.

When sliding it into place, the paint and primer scraped and peeled away from the original white laminated side. Honestly, if I were just going to hammer it into place (with nothing around that could possibly scrape at the paint), this paint job would have worked just fine. But the Ikea Billy has you sliding the backboard into these vertical slits and then hammering the thing along the horizontal supports. Perhaps if I were to sand it well before priming it would have worked better (but honestly no set of directions mentioned sanding), or if I had not used water-based primer and paint, but I'm pregnant and not about to subject myself to higher VOC products.

I actually was able to scrape all bits of paint and primer off the laminated side of the backboard that I had painted. I went to Plan B, which I had immediately thought of right after I started priming. I flipped the backboard over to the unlaminated, cardboard-looking side and primed and painted that. The paint stuck, no problem. And now, if we're ever tired of the aqua, we can always flip the backboard over and revert back to the original white.

Here's a pic of the bookcase with a bunch of baby stuff we've been storing up all around:

I absolutely love the result!
