It was an old paint roller with gravel hot glued onto it. When rolled onto the foam, it made sweet indentations for drybrushing.
The first arch was pieced together from individual stones and then realizing we had to do 10 arches we needed another plan.
The redwood was cut from a fence railing and stained. Pegs were added to hand sacks and other stage dressings. We did not want an arch in the stable, but a framed door, so part was cut away.
Other wise we think it looks pretty darn nice.
