DAD

Oasis is the foam made specifically for flower arranging. It’s used extensively in the making of funeral flower arrangements.
Florists construct frames of Oasis to spell out the name of a dead relative or friend from simple names to golf clubs, cars, fish – anything that the family feels represents the memory of their loved one maybe through a representation of their favourite hobby or pastime.
Oasis when used this way is literally a memory foam.
Here is DAD. An OASIS frame without the flowers.
