Home Depot: spray paint, spray paint primer (for three trays, next time I'd buy 2) , and tarp.
Round 3: Spray second coat. Let dry for 24 hours.
Don't they look fabulous? It makes me so excited to use them! But it's important to mention these trays aren't dishwasher safe or food safe. I plan to use doilies, parchment paper, cupcake liners, or scrapbook paper to place the food on.
Now, on to my next project :)
