Usually, Mrs.
C is the
artiste en residence', but I've done some acrylic work. The canvas can be bought already boxed, but one should learn to box (stretch) them oneself, just for added expertise but also for sake of cost. It's fairly easy to do... here's a link for guidance:

The raw canvas is prepared differently from use with oils... a product called
gesso is utilized and makes life much simpler when using acrylics. Obtain one for use with both oils and acrylics. Most products have directions for use, but, generally, I find it takes two or three coats with a very light sanding between each. The product is very fast drying. It's also a little easier to use, since it is fast drying, when cut with about equal amounts of acrylic gloss and water in a mixture.
Another convenient thing is that the gesso can be cleaned up with warm soapy water... but do it quickly, since it dries so fast. You won't be able to clean the application brush if you let it dry.
If you have experience with oils, it will serve you well with thinning acrylics from the tube. You'll have to experiment on your own, but it's easily learned.
This link (same source as previous) will be helpful in furthering your education. Best of luck!
