This is such a cool idea. I read about it on Cool Tools. Random people submit ideas and recommendations for their favorite tools. A lady who was traveling wrote this review.
Watercolor Tin DIY (prices vary)
(Use Fimo air-dry clay [$5] for paint reservoirs)
“People have started taking old Altoids mint tins and squirting tubes of watercolor in them and they sell these little paintbrushes at the art store. I was in London a few weeks ago and I was staying in a nice hotel with nice stationery. I pulled out my little tin and I painted a picture of The Ritz hotel while sitting having a coffee and popped a flower I had pressed in there and mailed it to my daughter who was back home.”
Isn't this a darling idea? If you are artistic, wouldn't it be nice to have a tiny watercolor set in your purse to pop out when you see something you want to capture. It's pretty easy to find the water. It would be fun making the paint reservoirs too. What a unique gift! I don't know about you, but I always save my tins. xo
