Today I made something so tiny that I can't get a picture of it. I've been wearing a rubber band around my wrist for weeks thinking about this, but I hadn't gotten around to it until today.
So, you know those really thin, square-edged rubber bands? Not the flat ones, the other kind. I figured, if you can cut it right, you could make tiny sugar cubes, and you can! It totally works! I had to discard about 70% of the ones I made for being misshapen, but it's not like it's a lot of effort.
Painting them white is the challenge. I tried coating my finger with white acrylic and rolling them around, but it didn't work as well as I wanted it to. I had coverage, it just wasn't awesome coverage, even when I did it twice. Then I painted the top of a Rubbermaid container (that's my workspace) with a little smear of white and rolled the little cubes through that! Much better. I just wish I could get a picture!
