Hi, im an amateur, so no laughing.
I wanted to put a garden border around my backyard. just wanting to fill it up with rocks/pebbles and plant a few plants. approx 800 of the wall, approx 12m long.
I have seen these sleeper 3m x 200 x 50. Thought about using them. Any ideas if thats sufficient and wont warp to much, and what would be the best way to fix them together, and to the ground
Thanks
