Lay 11 pots side-by-side to make a circle. Tack pots together with a spot of hot glue, top and bottom.
Run a bead of Landscape Liquid Nails into the joins between pots and across adjacent bases. Smooth with a wet finger.
Lay a second layer, using 8 pots, on top of the first, gluing sides together as before. Adhere to the base layer with Landscape Liquid Nails.
Finish 1 half by placing 2 pots in top and glue together. Repeat Steps 1–5 to make the other half.
When glue has set, invert 1 half, run a bead of Landscape Liquid Nails along edge of each pot and push halves together. Set and plant up.
