I’ve already presented the Lace Polymer Clay Bowl.
The lace bowl works similarly, they only use efaplast, an air-drying modelling clay. That makes it still easier :)
I didn’t find out whether this air-drying modelling clay is food safe, I don’t suppose so.
In the comments there are also nice inspirations:
– make an ornament for fir green this way,
– press lace from her wedding gown and
– leaves in the modelling clay.
