Because the workshop cannot run without enough flowers in the bank, adults are essential. Children can generate many smileys with their stories, but they cannot by themselves guarantee the financial side.
Adults: - buy the flower marked books - join book clubs or Caring Loving Tokens circles as members - invite local sponsors to plant larger flowers - give their own time and skills as additional smileys
In this way adults are both Flower Planters (with money) and Story Gardeners (with their time and experience).
The design makes this visible. - Adults see that their money is necessary but not sufficient. - Adults see that their time and stories are valued alongside cash. - Children see that adults are willing to give more than money.
