I'm thinking of putting French cleats every foot up the side of the wall starting at 4' high and going up. To make the cleats I'm thinking of using
1x2 fir and cutting a 45 on the top side, and attaching them to the wall with 2" screws.
my question is, are the fir 1x2's going to be strong enough, or should I use
3/4 plywood cut into 2" strips with a 45 cut at the top.
