Are you looking for gum nuts and gum blossoms, or the gumnut babies?
After May Gibbs died in 1969 copyright on her work passed on to the NSW Society for Crippled children and the Spastic Centre of NSW.
I agree with Meganne. Be careful if you download the gumnut babies, free, from any site.They may not be legal designs.

Glenn Harris has some gum blossoms on his site.They can be found in Wildflowers.
