If you're like me and you like to paint away from home, but don't have a safe way to transport your brushes, you can use just take an empty M&M's Mini's tube, cut your brushes to length, and pop them inside! Quick and easy, you can take your brushes on the road, and they easily fit in a jacket pocket, backpack, flashlight-holster, etc.
Note: It would definitely be helpful to store the brushes with their plastic bristle protectors on. If you don't have any, use various straws cut slightly longer than what you need to cover.
Also, I'll let you know that this made my brushes smell like chocolate (I didn't clean it too well), so try to resist the urge to munch on your brushes when they're loaded with paint! =P
