So, I finally took a chance at making my own holds for the wall.. and after a very little bit of experimentation, they’re starting to come out great!!
There are several examples of how to do it online, so I’m not going to rehash.. but I used this stuff (all from Home Depot)
and poured the holds..
More pics soon of the final products..
I think the biggest issue to overcome is the texturing.. still working on it, but it seems that using real rocks to create the surface texture works pretty well
