A New Home for my Collection

My wonderful father, an engineer and hobbyist/carpenter, built me a new shelf for my apartment after I was complaining about having nowhere to store my polishes. Look what he came up with! It's 7 shelves (one more than in the picture) because I anticipate adding quite a few more (I have 3 Julep polishes coming in the mail and I know that I will not be able to resist the new Germany collection from OPI!). It has one inch plexiglass slats on the front so that the bottles won't fall out but I can still check out all my lovely colours! :) I'm so excited if you can't tell. I used to keep them all higglety-pigglety in a box which is really bad for them, I know, I know. I currently have them ordered somewhat by colour and I'll probably keep it that way, at least for a while. How do you guys store your polishes?
