DIY glitter! Preheat the oven to 350. Place salt (table salt/sea salt) into a small bowl. Add drop of food coloring and mix with the salt. Spread mixture onto a baking sheet in one layer. Bake in oven for 10 minutes. Let cool, then transfer into a storage container for use. -- I put into old spice containers so I had a handy shaker, it worked very well!
