I've used pretzels to make a butterfly craft before, but that was a savory project suitable for young children. This is a sweet craft, better for preteens and up. I had a lot of fun figuring it out as I went and I'm happy with the end results. Affiliate links below.
Pretzel Monarch Butterflies
Place a sheet of parchment paper underneath a wire rack. Prepare the black candy melts following the directions on the package. For each butterfly, dip two pretzel twists and one pretzel stick into the melted black candy, then transfer them to the rack. I used a sharp knife to make the pretzel sticks shorter; whether you need to do this or not depends on the brand you use. After the pretzels have sat for 30 seconds, transfer them to a different part of the rack so that they don't stick. Let them set completely.
You'll be melting more black candy, so don't clean that container yet.
Move the rack, then transfer the pretzels to the parchment paper. Prepare the orange candy melts. I experimented with different methods of filling the holes of the pretzel twists with orange (see failures below). I found the easiest and most effective method was spooning a dollop of melted candy into each opening, then using an extra pretzel stick to push it over the black candy. The goal is to leave a thin border of black between the orange areas.
In retrospect, I should have used the scribe tool to get rid of the peaks in the orange that the pretzel stick left.
When the orange has set completely, prepare more black Candy Melts. Use the scribe tool to draw lines of black candy across the orange to mimic the patterns of a monarch butterfly. Symmetry is more important than accuracy, so work on both the left and right wings at the same time so that you end up with matching pairs. Let the black candy set. Don't clean the container or the scribe tool - you'll use both again.
Prepare a small amount of white Candy Melts in a separate container. Use a clean scribe tool to put dots along the outer edges of the pretzels. Again, work in pairs and focus on symmetry. Let the white candy set.
Crumple a small piece of foil into a cradle to hold the butterfly wings in the position you want. Do this for each of your butterflies. Carefully remove the pretzel twists, keeping the stick pretzels in position. Melt more black candy. Working on one butterfly at a time, use the scribe tool to paint a line of melted candy along each side of the stick pretzel, then gently place the pretzel twists back into position.
Reinforce the wings by adding a bit of extra black candy along the point where the wings meet the body. Let the candy set completely, then remove the butterflies and place them onto frosted cupcakes.
Happy spring, everyone! Celebrate with a cupcake.
