Now lets look at the circles in this scene.

There is a geometric way of working out the exact ovals in a perspective scene but the easiest method is to realize that the further away (Above or below) a circle is from the Eye Line (Horizon Line) the more pronounced are the curves. So note the basin under the draining board to the right of the sink. The top is a straight line. Now look at the bucket under the sink. The bottom of the bucket is a very shallow curve in a concave cup shape. Whereas the top - which is above the EL, is a very shallow convex curve. See also the coal bucket on the far right where the same principal applies. Contrast these shallow curves with the lampshade which is the furthest curve from the Eye Line in this drawing and see how sharp the elipse is at this point.
Still confused? Here's an illustration from my, as yet, unpublished book on stage scenery painting.
Notice the centre plate is at the eyeline of the audience so is flat. Whereas we/she are looking down on the one below her eyeline and up under the one above her eyeline. (I made this picture Eye Line the same as the lady's eye level to make my point). And if you want to see this principal in action look at the curve of the clown's hat where it meets his hair then compare that with the curves of the bottoms of his trouser legs.
What canvas do I use? I have already answered this one in my Q and A page re rolling canvas. (opens in separate window)

And finally what fireproofing do I use?

I use "Flamecheck" which is a spray that I bought from Harpenden, Herts via my theatrical suppliers. But Flamecheck would appear to have gone out of business. However Rosco do several types of fire retardent solutions and when I run out of my Flamecheck I will be buying from them. If you can't contact them direct go via your Theatrical Supplier.

Hope this answers your questions Ginny.
