25mm war gaming bases with recessed areas for your preferred water effects: pools, swamps, toxic chemical spills, or the like. I also included a plain 25mm base if you just want the basic solid version.
Inspired by the Youtube video "How to make a base with puddles?" by user Buypainted. Check out his videos. Lots of great painting tips.
UPDATE Aug. 23, 2013: Two new puddle bases added, "work-in-progress" tag removed.
