Line a baking sheet with parchment paper.

Melt fall-colored candy by heating in the microwave for 45 seconds, stirring, and repeating until melted and smooth. 

Flip Reese's candy over and place them on the baking sheet. 

Drop a small amount of the melted candy onto the bottom of each Reese's candy. (It may be helpful to use a piping bag and fill it with the melted candy, then squirt a little bit on each candy.)

Dip 1/4" of a pretzel stick into melted candy on the bottom of Reese's cup. Make sure the pretzel stick is standing straight. 

Place in the refrigerator for 10 minutes to set up.
