Amazon or buy the fondant cutters at the craft store.
Cut 1.5" sections of an English cucumber.
Halve them lengthwise and lay the pieces flat on a plate with the peel side up.
Cut a straight section of the cucumber to make the brim for each hat.
Add a thin slice of American cheese band and a square of cheddar to make the buckle.
Punch out a few clovers (or use a small flower punch) from the flat slice of cucumber then cut and add a stem.
Happy St. Patrick's Day!
