This one is super easy, heres what all you'll need (two are my new best friends)
Pour out some paint and make your dots! it's good to stamp the dot a couple times on your palette/scrap paper, because you don't want too much paint on it. You want nice, even dots, not globs.
I ended up having to do my dots twice, I could still see some of the black showing through. No biggie!
All done, now I have new shoes for my trip to Montreal tomorrow :)
This method can be used on a plethora of things, all you need are the dotters and Martha's magic paint. If I come up with any real cool ones, I'll be sure to post them here.
