A rope bracelet - reminds me of making friendship bracelets back in the day. My right second toe used to go numb because I'd hook the end of the bracelet over it, and then knot embroidery floss for HOURS.
Next, cut a tiny hole in the tip of the bag. Make a spiral design starting in the middle of the brownie and going all the way to the edge. Then, drag a toothpick from the center of the spiral to the outside it look like a spiderweb.
