Pizza Box Stepping Stones

I saw this garden project in a book titled "Trash to Treasures 1" by Leisure Arts.  These stepping stones use mostly recycled items.  The only item purchased was brick mortar.  The bag cost me about $3.00 and I used 1/4 bag so the stepping stones cost just .75 for 2. 
The recycled items are:
pizza boxes - I made a 13" and a 9" stone
dry cleaner hangers
dry cleaner plastic bags
pebbles, tile, shells etc.
You will also need:
duct tape
sand paper (optional)

Cut off the top of the pizza box. 

Reinforce the sides of the box with duct tape.

Line the box with the plastic.  Creases in the plastic will mean creases in your finished stepping stones so smooth it out as much as possible.  Some of it can be sanded down later but you can't fix everything.

Use the clothes hangers to reinforce the stepping stone.  For the larger stone use 4 hangers.placing one of the "hooks" in each of the corners of the box.  For the smaller box I twisted the hanger and placed it inside of the box.

Mix the mortar with water using an old bucket and shovel.  I don't know what's in the mix, but be safe and use a dust mask or some other covering over your mouth and nose.
The best consistancy of the mortar is slightly thick.  If your mix is too thin your decorations will sink, if it's too thick they won't stick when the mortar is dry.  Pour the mortar into the boxes, smoothing it out with the back of the shovel.

Next comes the best part, the decorating. This would be so much fun to do with children! 
I used leftover tile and pebbles from our patio and yard.

I let the stepping stones sit through a couple of hot days to dry completely. 
Using a stiff scrubber I cleaned off each of the tiles and stones, then used a damp cloth to wipe everything clean. 

Tip the stone out of the box and pull off the plastic.  If you have some rough edges you can sand them down, but I think they look a bit rustic and plan to leave them just like they are.

Be well and happy gardening.
