I was going through my "horse training" files on my computer and stumbled across this... some ideas and plans to build cavaletti.
The concrete molds are of course meant to be boxed frames into which one would pour concrete to create as many pole holders as necessary. I haven't really tried this one out, but concrete is both cheap and heavy enough to make a nice stand, I would think. If you have tried any of these or have additional ideas, I would love for you to comment!
