This is a little time consuming but well worth it!
You'll need Flakies from a beauty supply or etailer. These are way to big to work in nail polish but well fix that! A small sharp pair of scissors. A funnel, paper funnels work just as well. A bottle of clear nail polish, no more than 3/4 full. And I like to put everything on a sheet of paper to catch the escape flakies.
Empty about half of your flakies into a zip bag so that you have room to work.
Start cutting down your flakies. I rest my hand over the top to keep them from flying around. Turn the jar and stir your flakies up as you cut so that you get them all.
When you have your flakies cut down to the desired size (a little larger than the tip of a medium ball point pen) Place your funnel in your clear nail polish and start adding your flakies a little at a time. They tend to clog the funnel if you put too much in at a time.
Now add a couple of Ballz (BB's) and shake.
You can add a few drops of colored polish or glitter if you like. That's it, you are ready to play with your new flakies!
