Here are One Charming Party's directions for this DIY:
1. Using a metal skewer, pierce one side of the gumball. Hold the top of the gumball steady as you guide the skewer (see photo). This will prevent the skewer from slipping off the slick surface of the gumball.
2. Flip the gumball over and pierce another hole directly opposite to the first hole. If you try to poke a hole straight through both sides at once, the gumball will crack.
3. The hardest part is stringing the ribbon. Use a large needle to thread the ribbon through the gumballs. Thinner ribbon is easier to string. Tie a knot between each gumball as you string it.images by Sara Westbrook
