You should first coat the terracotta rose pots with
clay sealant from the inside. This ensures that the pores of the terracotta are sealed, no liquid subsequently penetrates to the outside.
Prime the rose pots with gray paint. As soon as this has dried, apply a second coat of
crackling varnish, and then a third coat of white craft paint after it has dried. This will now dry with the crackle effect to an antique look.
If you only want to design part of the terra cotta pot, tape off the areas that will not be designed with masking tape.
Coat the pots with napkin varnish and now design the surface with
napkin technique: place the top printed paper layer of the napkin, smooth the napkin motifs on the designed surface with a brush and napkin varnish. This will fix them at the same time.
