This is a light-weight design. There are three sawhorses arranged in a U shape. A sheet of white Plas-Tek and a some carpet scraps protect the ground from being pulverized into dust, and keep the boules dirt-free so that I don’t have to be cleaning them all the time.
From the sawhorses I’ve hung a 10’x16′ baseball net (from Networld Sports), folded so that it is 5′ high by 16′ long. The upper edge is hung from the sawhorses. The lower edge is held close to the ground by cords threaded through the net. The boule-return device is a pipe made of three 10′ PVC pipes.
Putting the boules in the boule-return pipe takes about one second per boule. Back at the throwing area, the pipe drops the boules into a bucket. I throw about 20 boules at a time. That is as many as I can lift in the bucket.
I lift the bucket onto a platform, so that I can easily grab the boules as I throw.
Here is another picture. You can read about the frame with the colored ribbons HERE.
