Make a tiny watercolor palette from a mint tin for on the go sketching!
Watercolors in mint tins were not my idea, though I can't remember where I saw them first! My addition is to lasercut the holes for the paints, because I could never make the holes-poked-in-polymer-clay version look nice.
If you're the sort who doesn't like instructions, the files for the lasercut bit are here. :)
Empty and clean out an Altoids mini mint tin (the lasercutter files for this tutorial are designed to fit that size, but you can also use them as a starting point for your own size tin!)
