Today I started a new work. This will be my largest to date, 60" x 40". It's two 30" x 40" cradled panels, side by side, bolted together and mounted onto screws sunk into a 4 foot by 8 foot, double-panel display wall. When the painting needs to travel or get shipped, it can be unbolted. Plus I can still pick it up and move it around when I want to paint on the floor or table. If this works out, the freestanding wall will do double-duty as an easel for large paintings in addition to being an extra display wall.
