They made canvas versions of some styles that already exist:

Penelope Satchel in Canvas

Legacy Slim Flap in Canvas

Carly in Canvas

Legacy Slim Tote in Canvas

Legacy Shoulder Bag in Canvas

Legacy Satchel in Canvas
I'm not really sure what to think about them. I like some of the spring colors... but I wonder how the canvas would look after awhile. Wouldn't it start to look dirty?
