Yes. I can paint my murals on either canvas or panels. How the canvas or panels are attached depends on the intended longevity of the mural in the space, whether it is designed to be mobile or not. Panels can be ordered up to 5′ x 10′ in dimension; a large mural may require serveral pieces fitted together.
At Santa Rita Elementary School in Los Altos, the school had a long term plan to build a new multi-purpose room, but were estimating five to ten years off until they would break ground on the project. In the mean time, they wanted to beautify their existing multi-purpose room and be able to repurpose the artwork when the building came down. I painted the interior murals on lightweight PVC panels and the exterior mural was painted on maximum density overlay (MDO) wood based panels.
Here are images from those projects:
