First paint your box/es.
Add decorative touches, like ribbon around the mailbox flag.
Stickers are one of the best ways to decorate your box. You can put them anywhere and everywhere; there are no rules. You can even put them inside.
Get creative with different pieces of decor. I'd found these cute pot of gold decorations, so we cut the stem off and hot glued the pot into a small hole poked in the top of his box. Jacob actually made his pot of gold into the handle for the mailbox lid. It turned out so cute.
Using the glitter glue, your child can also add their name to the box.
When all is said and done with decorating, you can finish off the boxes with a bit of glitter spray to make them shine.
You can trim with garland, as well.
And that's it. Now you're ready for the leprechauns!
