I believe it was the weekend after Christmas mom and I went to the ARC store closest to them and we found 5 of them all in good condition. They were all on sale (not like it mattered because they $2.99 for the 3 smaller ones and $3.99 for the two larger ones. The total of all of them is still less than paying for ONE of them in a store) so of course my mom got them. The only downside was that two of the smaller ones were this NASTY burnt orange, one of the large ones was a dark purple, and the other large one was gray. I told mom I could make them any color she wanted, so we settled on white.
Now I knew I could do this because I did it already. I happened to find a white one at an ARC store, but I wanted to match the other stuff in my room, so I wanted it to be espresso brown.
It is actually surprisingly easy to make them into any color you want. I am working on all of moms right now.
All you need is primer (if it a dark color), and whatever color you want it to be, varnish, and some paint brushes. I would also suggest using paint tarps to protect the surface you are painting on.
First you prime the shelves. I do about two coats depending on how dark the previous color is, as its easier to paint if you prime it better.
Obvious let it dry before you do another side, which can take a while if you did a thick coat. Once you have primed it to the best of your liking (i.e. you can't see the other paint through the primer coat) you can start painting it the color you actually want. In my case its going to be white, so the primer acts as a real bonus for me. So far I have coated the small ones twice and they are pretty much done. I just have to check for random spots I missed.
Once everything is completely dry (I am going to let them sit over night) you can do a coat of varnish. Now this step is done to seal the paint and also to make it look more "real", or like it was always meant to be that color. Once its been painted and dry you notice the dull look to it. The varnish will make it look shiny. (the above picture reflects the varnish.) It looks like it came from the store this way now.
So if you come across a shelf (does not have to be just a floating shelf) and you would like to change the look, this is an easy way to do just that.
