In the painting I am now working on 'vinegar and onions', I toned the canvas with a raw sienna thinned down with linseed oil. I am using water mixable paints, and used the linseed that came with the set. I didnt wait for it to dry before beginning the painting (which was probably not a good thing), and although it didnt seem to affect the painting of the still life items, it may have affected the background. When applying the background colour, it seems all blotchy. Waiting another day for a second coat produced the same results.. which to me resembles the appearance of suede, when you run your fingers over it.. changing the 'nap' of the fibres. I assume that waiting until the background is dry will allow me to proceed with another layer which wont do this, but my real question is- how should I be toning a canvas with for water mixable paint? Would a wash of acrylic have been a better choice?
All my other oil paintings I just painted directly on the canvas, so didnt have this problem. Also, how much difference does toning a canvas really make in the end result, if it is all covered over with paint anyway?
Apologies for my very basic questions.. just trying to understand how oils work, and why.
