This natural decoration is made as follows:
Paint some wooden balls as desired with craft paint. Tip: Use a bamboo skewer to hold them in place.
Now arrange the painted and unpainted balls into towers of different heights (the bamboo skewers can also be used to help hold the towers steady until they are glued together). Glue them together with craft glue. Make sure that the hole remains open so that the dried flowers can be inserted later.
Drill holes in the tree discs, e.g. with a Dremel drill, for branches and dried flowers. Fix them in the holes, if necessary with a little glue. If necessary, lightly mark the places where the balls are to be placed.
Glue the ball towers onto the branch discs with craft glue.
Now you can decorate the towers and holes with dried flowers as you like.
