Cut your watermelon in half and scoop out the flesh using a melon baller to create perfect round pieces. Alternatively, cut the watermelon into thin slices, then use a star-shaped cookie cutter to punch out star shapes. This takes about 10 minutes but makes such a difference in presentation.
Pat all your fruit dry with paper towels before you start threading onto skewers. Moisture makes everything slip around, and trust me, I learned this the hard way when my skewers fell apart at a party. Dry fruit threads so much more smoothly onto wooden or metal picks.
Arrange your fruit on 8 skewers by alternating watermelon stars with strawberries, blueberries, and pineapple chunks. Thread one piece of each fruit, then repeat until your skewer looks pretty full. I usually do about five different pieces per skewer to get that colorful look.
Whisk together your honey and lime zest in a small bowl, then drizzle it lightly over each assembled skewer. The lime zest brightens everything up and keeps the fruit from tasting one-note. Don't use too much honey or it gets sticky — just a little goes a long way.
Sprinkle the white chocolate chips, mini marshmallows, and chopped pistachios over the top of each skewer. These add texture and make it feel extra special without requiring any cooking. I scatter them randomly so it looks homemade and cozy, not overly fussy.
Chill your homemade fruit skewers in the refrigerator for at least 15 minutes before serving. Cold fruit tastes so much fresher and juicier than room-temperature fruit. Pop them in right before guests arrive so they're perfectly chilled when everyone digs in.
