This weekend I had one of those oh-so-simple ideas that leave you wondering why it took you so long to tumble to it. I've been painting lots of small wooden buttons and feet, and until yesterday, it was fiddly and annoying, and then the light went on!
I took a bamboo chopstick with flat sides, ran a strip of narrow double sided sticky tape along one of the sides, then stuck the buttons onto the tape. Painting was a breeze after that. I can now paint the entire surface in one go, with no paint smeared fingers or blemishes on the material. Once the objects are dry, I peel them off the tape, then peel the smeared tape off and dump it in the trash can.
