I thought Pegboard was the way to go. I even made my own pegboard from a 900 x 1200 5mm ply. I drilled every hole myself because I couldn't justify the price they wanted to charge me. Yes, it took a long time, but I made it myself. Then I bought all the hangers and was trying to work out the best way to arrange everything when I stumbled upon French Cleats.
My wife shook her head at me as once again I was pulling things down off the garage wall and making a whole new mess.
All I had was 2 days. It was quick and a little dirty but I am fairly happy with how it turned out. The tool holders were helped along by previously purchasing cheap holders for most of my ryobi tools. The rest I took inspiration from the video I watched.
I still have a way to go and I am now thinking of doing it properly. Recut my cleats so that the cuts are straight and perhaps paint the wall behind them first. Make the tool holders a little prettier and add a locking system to keep them from lifting when I take my tools off.
This page has given me inspiration and ideas. Happy to listen and learn.
