I've been pricing wet canvas carriers...and they can be costly! For these little paintings, I usually just tape them inside a plastic flat container. However, that wouldn't work if I had to travel any amount of distance, so I'm upgrading. If anyone has any favorites they would like to share, I'd love to hear. Right now I'm leaning toward Guerrilla totes.
