I found this picture on Pinterest and used it as motivation for this craft. I tried covering the "B" in pennies but it had awkward spaces between coins and didn't look clean. There are so many options for decorating letters with coins: filling, outlining, designs, etc. I happen to love the copper color pennies provide but you can use dimes, nickels, or quarters if you prefer silver. The different sizes of the coins allow you to have some flexibility with the shapes and sizes of the letters.
The best part about this craft? All you need is hot glue, coins, and a base letter!
