For the last few afternoons I have been taking my secateurs for a walk. After watching the sunset I return home with a bag full of plant clippings.
Radically (for a glass caster) I have just been making plaster tablets from the impressed (unimpressed) plants. After being rolling pinned into the clay, plants carefully removed and the plaster cast, the resulting detail is fantastic.
I do have plans for these casts, to be revealed later!
