Garage Fold-down workbench - I've always wanted to do something like this in a kids' art/play room. This website also has a lot of great ideas for creating more storage in your garage. I look forward to using some of them if I ever have a garage.
I was just trying to design one of these today, using the ikea tables that fold into wall. They were too small. I'd want a folding craft table tho! Exactly what I need for my house! Just smaller and folds the opposite way
