I went to a dollar store looking for tin boxes to create an instructable that I could use. I found a Sucrets Complete tin of 18 lozenges, packed in three tiers of six each, in their own individual plastic wells.
I removed each of the lozenges from the three trays, and saved them for a future cold. The hardest part was removing all of the foil from the plastic.
After removing all of the foil, and washing out each tray, I filled them with my own watercolor paint. I added a few drops of water, to each color, to dilute, and even out the paint in the tray.
I repeated the previous step with the other two trays. (The hardest part (again) is removing all of the foil.) Now I had three trays with eighteen of my favorite watercolors. I let all of the paint dry completely. I then cut out three seperator sheets (from any thin plastic) to put between them, to keep them from seating into the above tray when stacked into the tin.
Now grab your favorite small brush and sketchbook, and go anywhere to paint. We will be going on a cruise, where packing is at a premium, so this will work out just great. I'll probably even bring my lozenges with me (just in case). Enjoy!
