Christine de Beer - effortless floral craftsman
Oasis floral foam is a wonderful sculpting medium. It carves and sands smooth easily and can be re-used as long as you do not actually use it as a water source.
For my touchstone vase I carved the basic shape out of a block of Oasis. I hollowed the shape out to be able to double line it with strong plastic making it water proof. Cut the plastic just below the rim of the Oasis shape
I placed a Kenzan into the container and filled it with water to keep my flowers hydrated. The leftover bits of Oasis are carved and sanded into smaller pebbles to cover the Kenzan.
If you use Papier Mache, terracotta or clay or any precious container that might scratch, rust, or discolour or disintegrate when it's in prolonged contact with water it is best...
