My office not only holds my makeup, it also serves as my photography studio which I talk about in detail here. This room is so multi-functional that if I could fit my exercise bike in here I would.
This is how I store my makeup brushes. I purchased these porcelain eggs all over the US. I found them all either on Etsy or eBay. I show them in detail in my Brush Storage Post here.
I bought these Black Leatherette Storage cases online 3yrs ago. I talked about them in detail and listed the website where I bought them from in my 2011 Blog post (link above). I absolutely love them and the drawers are very deep which you can see if you visit the link above. I actually bought an extra one of each (tall & sideways) just in case I need it. I could probably store my blushes, foundations, skin finishes and palettes in them but I store those in the silver Helmets because there's more room.
Below is the Helmer, I only took photos of the contents on the right side, the Helmer on the left side contains all hair clips and the bottom two draws contain nail stuff. As you can see, the drawers are very roomy, you can purchase the metal or plastic trays to organize your stash or just toss them in like I have in a few of mine.
This is where I store all of my accessories. All the drawers are stuffed full but I have close ups of the jewelry Armour here. I used to have an earring carousal sitting on top but I ditched it because I wasn't wearing all that godly jewelry any longer.
My perfume is sitting on top of my Armour on a large circular glass platter. I have a tall crystal vase that holds all my tiny sample vials, here's some close up photos. I love collecting them and I always try and ask for one or two while i'm out shopping.
