Small effort - big effect!
For this idea you need two approx. 25 cm long wooden sticks, possibly from a beech round stick, Ø 10 mm cut to size
Prepare rose pots
Prime the rose pots and the round sticks with white Handicraft paint, and let everything dry. Place the roses with the Pearl-Pen effective small dots around the edge of the rose pots.
Now simply fill the rose pots with putty and cover them with green moss. Fix the Iceland Moss with straw flower needles. Stick the round sticks into the pots.
