What a beautiful thought behind this project, @mlb_diy, I'm loving it. It's so heartwarming to see your son involved in this build too, and doing something wonderful for his peers. Did he enjoy the process? The bench itself looks lovely, and I'm sure those bright set of colours will help in brightening up someone's day.
He loved helping with the design and had a go of all of the tools etc. My daughter made sure everyone knew that she was the one who chose the colours though! When we delivered it to school, he gave a speech and explained what it was for. He was so proud of himself, as was I.
Since dropping it off, he said that it has been used a lot for both it's intended purpose, but also a central point where they play games from and just hang out. Perfect!
