I've tried to be quick and to the point with the text, because I know that although the instructables with tons and tons of writing are usually the most informative ones, they're also usually the one's that get overlooked fastest.
Step 1: Calculations
At this point I also made a prototype in the front yard.
Step 2: Get Some Bricks
Step 3: Unload
Step 4: Landscape Fabric, Bricks, and Gravel
After the landscape fabric was down, we set the bricks up as the labyrinth's outline, and tweaked it.
When the bricks finally looked right, I poured the gravel into the labyrinth's outline to make the path. Then we smoothed the gravel out to make a nice, even layer.
The last part of this step was to trim the landscape fabric around the labyrinth.
Step 5: Take-Away Rocks
Originally I was going to stencil letters of the alphabet and mini labyrinths onto pebbles, but it soon became clear that this would be too difficult. I considered stamping the rocks, but eventually resolved just to use pens. I also abandoned the idea of using letters, and decided to use words (and symbols) that (I thought are) meaningful. My list included:
energy, inspire, eternity, invent, learn, illuminate, adapt, mystery, cherish, love, peace, unity, treasure, nurture, create, creativity, renew, transform, rejoice, soar, contemplate, truth, beauty, and meditate
...as well as some others. Once I had my list, all that was left to do was to draw on the rocks.
Finally, I placed the rocks in a pretty bowl I had picked up at Ikea, and we were good to go.
Step 6: Poem
I chose a large, flat rock from the beach and slathered it with clear medium (glue). Once the medium was on, I placed the poem on the rock and covered the whole thing with medium.
Step 7: Finish
I got a great mark on the project, and everyone in the school seemed to like it.
