We have wood fences, how about using all this excess stone to make stone walls (with a wood gate)

Nice idea. Added

or stone flooring maybe about 50 per floor ^_^ lolz

Maybe use stone to make deep water into shallow water.

stone into a sidewalk for bots to walk faster on?

or to upgrade the little huts....

or change up the Tools: wood tools low durability, stone tools med durability, and metal high durability. 

for now just allow them to be recycled to nothing until we come up with something.  tree seeds 2.

Also maybe:

Stone huts 

Stone statues

Stone paths

Stone tools
