Proteas are fabulous as dried flowers. They have great sculptural qualities and they keep their structure well, not falling apart easily. There are no real tricks to drying your proteas - you don't need to hang them upside down, although it doesn't hurt. Just as long as they are dried without being too crowded, to make sure their shape remains intact, and to allow for airflow. Some even keep their colour well.
You can get fancy if you want to - the following are some ideas from Proteaflora, a major Protea nursery in Victoria.
Hanging
Pick the flowers in their prime, strip off the bottom leaves then tie about 5 of the flowers together in a tight bunch with a rubber band. Hang them, heads down in a dry, dark, airy spot for about two weeks.

The pink flowers pictured are Protea Pink Ice. There are some others mixed in including Brunia Albiflora, (press the link to check out more of these) and some Leucadendron Argenteum. I am also lucky enough to have a huge Banksia Grandis tree and the seed pods often come on long stems which make a great display.
So next time you have a bunch of proteas, think about drying them for longer lasting loveliness!!
