Well, it's actually quite simple! First, you'll need to measure the length of your tree and cut the mesh ribbon to size. Next, you'll want to start at the top of the tree and drape the ribbon around in a spiral pattern, making sure to tuck the ends in as you go. Once you've reached the bottom of the tree, you can secure the ends of the ribbon with a few pins or tacks. Lastly, you can add any additional decorations like ornaments or lights to complete the look!
