Terra Cotta Barrel Tiles Tutorial - the Trash to Treasure Way

I used two shades of orange, light buttermilk, burnt umber, and honey brown paints. I just mixed the colors on the brush and randomly painted the toilet paper tubes and the valleys of the corrugated cardboard. The valleys act as the upside down tiles on a real barrel tile roof. The tubes are cut into roughly half inch by one inch tiles. Each tile is glued over two of the cardboard ridges. In the third photo, I am using chopsticks to hold the edges of the tiles down until the glue sets. This is an experiment that's going to work! That always makes me smile. :-)

Edited: Here's today's work. I've decided that painting the corrugated cardboard is not necessary. You really can't see the valleys but they help so much with spacing and shaping the tiles. Just painting the tubes, cutting into tiles and gluing them on takes a lot of time. I spent several hours working today. I filled in the corrugated board on the angled left side and finished the three bottom rows, then added two more full ones. I also added a couple more colors of paint in the brown family. I like the variation - really makes it look like aged tile. This is going to take some time but I am very happy with the way it looks.
