Large gumnuts are found on a variety of Eucalypts, and are fantastic for crafting. These little Christmas Angels have large gumnuts for their bodies, and bow-tie pasta wings. The Angel on the left has a sheoak head and gumnut cap hat, while the one on the right has an acorn head and acorn cap hat. Alternatively, you could use wooden beads for the heads. Little plastic eyes finish them off, and the pieces are glued together using a low-melt glue gun.
Great review of Nature Crafts with Common Plants in the September 2017 Gardening Australia Magazine (page 11).
