Wash and gently dry your tomatoes and grapes.

With a sharp knife, cut a tomato in half on the diagonal. Flip one half of the tomato over and push the two cut edges together to form a heart.

Use a cocktail stick or bento pick to pin the two halves together. Repeat with a grape.

To make the skewers, repeat as above but thread onto bamboo skewers, alternating between tomatoes and grapes.
