Someone asked recently if you can paint in a larger format on Judson's 9x12 Guerrilla Painter Box. You can! I regularly paint 12x16 on my box by using the telescoping easel kit. Since it's hard to describe how this works, I thought I'd show a few pictures.
The mast has a little hook at the top that holds the top of the panel. The bottom of the panel rests in a little metal bracket, which itself hooks onto the two built-in brackets in the lid. I also use a heavy-duty knob on the lid,which allows me to give the knob a little extra twist to really secure it.
The mast and the bracket are all part of the telescoping adapter kit.
Although the mast will accommodate a larger panel, I stop at 12x16 - you are still working with only a 9x12 palette, and I like to have a larger palette if I go bigger than 12x16. (You can, of course, get a palette extension kit that will expand even that.)
