Line two baking sheets with parchment or wax paper. Set aside.

Melt red candy melts in a tall microwave safe container (ex: liquid measuring cup or mug). Stir candy melts every 30 seconds until melted.

Dip half the pretzels in the candy melts, rotating to create an even layer of coating.

Place dipped pretzels on prepared baking sheets. Sprinkle with red sanding sugar.

Repeat steps 1-4 with blue candy melts and blue sanding sugar.

Let set, about 15 minutes.
