This is the new project I started. It is for a fundraiser for the local arts theater the Colonial. The twist is that it is a tray, as the benefit is named "Tray Jolie."The tray is metal and is primed for oils, so that didn't help ME much! So what I did was cut some pastelbord to fit in the bottom of the tray. I needed 3 boards to do this as I didn't have any boards the right size. When I finish it, I'll varnish it and then glue, or maybe caulk, it to the bottom of the tray, fill in the edges and then paint it out black. Any ideas on what could work to adhere the pastelbord to the tray would be most helpful!
