I start with the almonds because they need time to dry before going anywhere near the pretzels. Melt the black candy melts in 20-second microwave bursts, stirring between each round until smooth. Using a fork, dip each almond completely, then set it on your lined baking sheet to harden for about 15-20 minutes.
While the almonds dry, I melt the green candy melts the same way, in short microwave bursts, stirring often so nothing scorches. If the color looks dull, I stir in a drop of green food coloring to brighten it. A spoon works great here for scooping and pouring the coating over each pretzel rod.
Using your spoon, cover about half to two-thirds of each pretzel rod with the green coating, then gently shake off any excess so it doesn't pool at the bottom. Lay the coated rod flat on the baking sheet right away, since you need to work quickly before the coating starts to set.
As soon as each pretzel rod is coated and lying flat, press a dried black almond onto the tip where a fingernail would sit. I press gently but firmly enough that it holds in place as the green coating firms up underneath it.
Once the coating looks set but is still slightly soft, I use a toothpick to draw a few small wrinkle lines near the nail and a couple of larger arcs further down the finger. This step is optional, but honestly, it's what makes these witch finger pretzels look genuinely creepy and realistic.
Give your witch fingers about 15-20 minutes at room temperature to firm up completely before you touch, serve, or store them. Rushing this step is the easiest way to smudge your careful knuckle lines, so I always find something else to do while I wait.
