I purchased this set to construct an outdoor climbing wall. Since I wanted our 4yo to be able to use the wall barefoot, smooth edges on the holds were a must-have feature. I haven't purchased climbing holds before, but I have to say that this pack was a winner. Even though there's not a huge variety in hold shapes, it's not a big negative. My little one loves the new climbing wall (my wife does too 🙂).
The How Tos section of the Atomik website has a fantastic tutorial if this is your first time building a climbing wall. I ended up purchasing a 5x10 sheet of 3/4" medium density fiberboard, painted it with the exact recommended primer (easy!), and then purchased a gallon of Cyberspace Rain Refresh pain with some texture mixed in. It looks AWESOME. Thanks again for the tutorial and for the awesome holds.
