It's that simple:
Choose small bottles or open glass balls as planters. Decorative little stones, coarser Sand or gravel is poured into the vessels. Decorative small plants (artificial plants) are then placed in this "planting soil", possibly arranged in bouquets.
For hanging up, natural Jute yarn is either wrapped around the bottle neck and then knotted or Yarn is knotted to the existing hanging eyelet of the glass balls.
Extra tip:
Choose a rustic twig, an old board or a round rod and arrange the planters as a harmonious group in different lengths on this hanging aid. The arrangement can be hung up and rearranged more easily.
