Rinse the grapes and strawberries and pat them fully dry, wet fruit slides on the stick instead of holding.
Toss the banana rounds gently in the lemon juice in a small bowl, this slows the browning for up to an hour.
Thread one green grape onto each skewer first, pushing it about 1 inch down from the top.
Add one banana round next, flat side down, so it sits like a collar under the grape.
Slide a strawberry on point up, hulled side down against the banana, so the point forms a hat shape.
Top each skewer with one mini marshmallow, pressed gently onto the strawberry point for the pom pom.
Stand the finished skewers upright in a short glass or jar so they hold their shape until serving.
Chill for up to 1 hour if making ahead, then serve within 2 hours of assembly for the best texture.
Good to Know
Assemble up to 4 hours ahead and keep covered in the fridge, the marshmallow stays put and the fruit stays crisp if it is not sitting in its own juice.
