This thread is for posting pics and "how-to make" palm trees, rocks, mountains, and related "desert" decor for classroom themes and sets (popular in the Workshop Rotation Model).
Feel free to post your pics.
One good source of pics and how-to's is pinterest's "Paper Palm Tree" search results.
Do it yourself palm tree...
FYI: Fiberfill makes great clouds, and also acts as a sound-dampener in "live" rooms.
Or purchase...
Party supply websites have a lot of palm tree and tiki decoration options. As seen immediately above, these cardboard cutouts are 6 feet tall and hinged so they can be individually bent. Typically about $5 a piece and last for years.
"Meaningfulmama.com's website has a great tutorial on how to make a fake palm using the an old umbrella (with its fabric stripped off) and plastic palm leaves from the hobby store wrapped around the umbrella ribs. The trunk is a paper tube wrapped in crumpled brown bags and slipped over a microphone stand.
