Here's an option for creating your own 10mm palm trees. I made these up for my WWI Middle East battles. I'm sure I can use them for other scenarios needing palm trees.
|Palm tree leaves.|
Aquarium plant, toothpick, coffee stir stick/straw, cork sheet.
Everything cut to size.
All the pieces put together.
Glued and painted up.
Trees in action (Battle of Gaza).
