Canvas (n) and Canvass (vi/vt)

Here, at the end of an unbelievably dismal, pointless day of work, is a set of five homophone worksheets on the noun canvas and the verb–used both intransitively and transitively–canvass.

If you find typos in these documents, I would appreciate a notification. And, as always, if you find this material useful in your practice, I would be grateful to hear what you think of it. I seek your peer review.
