If this idea is already on Pinterest or somewhere else, then forgive me, but I was in the Studio and started to throw away an empty water bottle when it dawned on me that if I cut the bottom of it out I would have a handy little container for whatever I need it for!! Right now I have cotton balls stuffed in one of them. I don't know about you but I am always looking for containers for all kinds of things.
Hope this is useful!
Have a good day in your studio!!
