Measure your vase circumference and trace with pencil (I wanted my vase to sit in the center of the planter, so I found a bowl that had the same circumference as the middle of my vase)
Using your scroll saw, cut the center circle from the wood
Find a drill bit that has the right width in order for the cord to pull through easily
Drill your four holes in the four corners of your block of wood
Pull your cord through each hole and tie a knot at the end to prevent your cord from slipping back through
Loop a knot at the top so you can hang your planter
Place your vase and plant in your new hanger and enjoy!
