you can also thread a string through one of the holes and hang it up
red is cut
blue is engrave
you can vary the size
but be careful to change both at the same time because it still has to fit on top of each other
when gluing together, check which direction it is turned beforehand
the petals all look very similar and once the glue is on top you don't have to do a lot of trial and error
(I had to turn 2 rounds for the right position :) )
