Step 2: Steps 1-9: Preparing the Fabric
Step 3: Steps 10-18: 'Sewing' the Fabric
Then, take the nylon twine and begin to ‘sew’ through each hole until the entire circle is complete.
Use your hand to hold the base of the circle down while pulling the excess nylon to create a sac.
Step 4: Steps 19-25: Inserting into the Subway Grate
Keep a hold of the nylon while pouring soil. Then, squeeze the small plant through, add more soil, and some water. Lastly, tie the nylon to the grate.
Make note that several changes have been incorporated into the procedure for making and inserting this prototype. See next set of images for details.
