Line a large baking sheet with paper towels and pat the fruit dry.
Thread 3 pieces of hulled strawberries, seedless grapes, and clementine segments onto each wooden skewer, ensuring the fruits cover the end of the skewer and are touching.
In a small saucepan, combine white sugar, water, and light corn syrup. Bring to a boil over medium heat without stirring.
Reduce heat to medium-low and cook undisturbed until a candy thermometer reads 300 degrees Fahrenheit (150 degrees Celsius), about 18 to 20 minutes.
Prepare an ice bath in a bowl filled with ice and water.
Remove the sugar mixture from heat and let it stand until bubbles subside, about 1 to 2 minutes. Tilt the pan to pool the syrup to one side.
Working quickly, dip the fruit end of each skewer into the sugar mixture, rotating to coat evenly. Allow excess syrup to drip back into the pan.
Place the dipped skewers, fruit side down, in the ice bath to cool for about 1 minute. Then place them, fruit side up, in a heavy cup or saucepan.
Repeat the dipping process with the remaining skewers and sugar mixture, trimming any excess sugar drips with kitchen scissors.
Serve the candy-coated fruit skewers immediately
