Plein Air Watercolor Palette using Altoid Tin

myminifactory

17.11.02 - 16 division added   Make your own mini plein air watercolor palette with an empty Altoid tin case. The bottom space is a bit larger than the entrance, so you might want to add a magnet sticker or glue them, but still works fine without any attachment, it doesn't move around that much. (I am not using any) For the upper tray, you can use this space as an extra storage, and it becomes a good mixing plate after acetone smoothing(cold method).
