Here, I've used a desktop mail sorter to display and organize my most-used eyeshadow palettes. I like this method because it allows each palette to stand independently and not move around when I pull one out to use. The sorter does not take up much space and I actually have another set on the other side of my 'beauty desk'.
In stores, this is sold as a 'mini sorter' or a 'letter divider/sorter' and you can usually find a fairly inexpensive one in the stationery section of stores like Target and Walmart or at an office supply store like Staples, OfficeMax or the Container Store. I got mine at Walmart for less than $5.
As always, thanks for reading!
How do you store your palettes?
