I also had a garbage can lid which made great trays for working - you'll see it later photos and most importantly, you need an assortment of forms to mold the concrete. I also had a bucket of water for rinsing.
The forms that I uses were salvaged glass light shades. I had four different sizes and had them nearby and ready to use. Materials include 'Quikrete' concrete mix and water.
