I didn’t realize how many brushes I had until I finally organized them into an acrylic storage cube I got at the Container Store last weekend ($9.99). Though I have quite a few, I’ve never spent a lot of money on any one brush, these are all E.LF, EcoTools, NYX, and Real Techniques with the exception of one or two that I received as gifts. You don’t need to spend a lot of money to get quality brushes!
I love the look of them in the clear acrylic. If you want to have them a little higher in the container, you could use vase filler from Michaels to suspend them in (some people use sand but I know that can rub off the lettering/paint over time)
