I am well into a building a pop-up that started with GlenL plans for the hard-sided Importer. It has changed to a pop-up. The plans followed the glenL design until I got to the cabover cantilever. After that, it's a different story. The box is nearly finished and then I need to build the roof and a lifting mechanism. I have ideas for both of those but I'm wondering the best way to attach the canvas. I'm open to suggestions.
