Pull the strands apart from the string cheese sticks, going about three-quarters of the way up. Hold a string cheese at the solid end with your thumb and forefinger wrapped around it; insert a pretzel rod into the top of the cheese as you hold it firmly. Tie two long chives around the top of the cheese, about 1/4 inch down from where the pretzel and cheese meet. Snip away any excess chive. Arrange these cheesy appetizers on a serving tray with more savory snackables.
