Melt each color of candy in separate bowls according to package directions.

Transfer about 2 tablespoons of each melted candy color into separate piping bags and set aside.

Dip the mini pretzels and pretzel sticks into the melted candy until fully coated. Remove using a fork and gently tap off excess coating. Continue until all pretzels are coated. Be sure to coat pretzel twists in matching pairs for butterfly wings.

Place two matching pretzel twists side by side on parchment paper while the coating is still wet so they stick together as they harden.

Add rainbow sprinkles to half of the butterfly wings.

Once the coating has hardened, remelt the candy in the piping bags if necessary. Pipe a line of candy down the center of each butterfly and gently press a coated pretzel stick onto it to create the body.

Use the remaining candy in the piping bags to drizzle decorative designs over the other half of the butterfly wings.

Allow the butterflies to cool completely until all decorations are firm before serving.
