I did this :) and made two :) One for Brushes and one for other stuff; eyeliner, mascara etc. I used a round shape bowl; found at Old Time Pottery four bucks each and found the rocks at Target for five bucks. Didn't fill mine to the top with the rocks. Came out really pretty and looks a lot better than all touching and clumped together in a cup.
