Yes Rebecca, they come in rolls of either full rounds or half round logs and vary in length. I edged a couple of paths with them years ago and they are still going strong. You will need some stout stakes, drive them into the ground until firm, now unroll the log wall and screw it to the stakes firmly. Saw off any off the stake above the log wall, stand back and admire. I did fasten heavy duty plastic to the back where the soil comes in contact as I raised the soil level.
Hope this helps Frank.
