To make your own custom glitter blend, pour equal amounts of your favorite glitter into a lid and shake. You can add more or less of a color until you’re happy.
You can use your finger to reposition your glitter while the glue is still wet.
Remove your tape then seal by covering glitter with a thin layer of mod podge. It will dry clear, but if you get any on the glass, you can clean it off with rubbing alcohol.
