Preparation of canvas I believe preparation of canvas is very important. I treat my canvas with primer first and then with gesso. I generally apply 2 coats of both the items so all of the canvas gets covered. I do not want one bit of canvas to be left out without the coat. These coatings will have immense effect on the painting. After the canvas dries for about 1 day after the gessor and primer application, I coat the canvas with one thick layer of oil paint. Then I allow the oil coat on the canvas to dry for about 2 days until it is completely dry. I allow it to dry in shadow, in the open space and then after it dries it is ready for painting. I will wash the canvas with the water, dry the canvas and then I start with the painting. If you are an oil painting artist, it is very important to know how to prepare canvas for oil painting, how to create grid, how to varnish a painting and then how to preserve a painting. What to do after the painting is over ? I allow the painting to dry for about 3 -4 months after the painting is over. I live in India, so it is very hot between March and August, so allowing it to dry for 2 months is enough for me. Then it is ready for varnish. Expert artists here allow painting to dry for six to seven months. They feel it is completely ready for varnish. Varnish is a tricky process. If it is done incorrectly, the painting may get damaged heavily. The colors on the painting gets removed and gets distributed everywhere if the painting if varnished before the painting is completely dry. Then it will be very difficult to correct the damage anywhere on the painting. If you have used the technique glazing or if you have used too much oil in the painting, it is safe to dry the painting for a minimum of 6 months.
Hi Ramya.how kind of you to put this tutorial together.  Nicely thought through and illustrated.  But  I'm not sure if you have noticed this is a forum where members chat, show work in progress and as in my recent case ask for advice..   A lot of the members here are experienced artists and have been painting on canvases etc for a great many years.  Probably before you were born. I may be wrong but I think it's not a good place for your excellent efforts.   Maybe ask the POL team and they could suggest a  better place for you. Or why not make a U Tube video then you will reach a much larger audience.  I could be quite wrong and others feel differently.  But this is my point of view .  
Excellent Ramya, and good advice for beginners! In the U.K. we generally wait 6 months or more before varnishing. I’m not convinced about applying a thick coat of oil paint over the gesso, I prefer a thin translucent wash of my ground colour to give me some transparency. I’m actually fine with this sort of simple tutorial on the forum, there’s so little going on anyway at the moment on there, and apart from the recent introduction of artists to highlight which I’m enjoying, (great idea Paul), there’s very little else to interest me if I’m honest. I don’t mean Sylvia’s forthcoming entry into teaching, and various other subjects, these are things that do interest me and I generally participate if I’ve got anything of value to add!
Following Sylvia's post, there is a 'Tecniques' section of this website which might be one such 'better place'. Anyone looking for a tutorial is more likely find it there than within a dynamic forum where posts are pushed down the page with each new entry. I know the difficulty I've experienced trying to unearth an 'old' post which I knew was hidden somewhere.
I have some problems with this as a process, mostly concerning the "thick layer of oil paint" after you've applied a primer and acrylic primer (called erroneously "gesso", but that's the manufacturer's error, and nearly all of them do it, not just Camel brand: it isn't gesso, but it is primer).  If you paint thick oil over the priming - and then wash the canvas,  what is the purpose of either operation?  Following this advice could lead to people using an oil-rich (and thus slow-drying) layer on top of which leaner (i.e. less oil-rich) colours are applied.  This is unlikely to age well it's almost bound to crack.  If you're suggesting using an oil ground, it should preferably be a lead-based Foundation White - i.e. not just any oil paint.  There would be no good reason to apply thickly, either.  I know some people use the Bob Ross/William Alexander method of painting into a layer of thinned Titanium White as an alla prima approach - but though there's not an obvious disadvantage to doing that when the paint is still wet, at least it shouldn't cause problems (provided it's not slick with oil) - but there's not really much of a good reason to do it, and that isn't priming, anyway. Another method, and there are many, is to seal the board or canvas with shellac, and then apply priming - of oil, or acrylic primer ("gesso") over that: or even shellac > "gesso"/acrylic primer > oil primer.   When you say wash the canvas - how would you do that?  I don't understand why you think that would be necessary, or even helpful.  I'm sure you don't mean you plunge it into the washing machine, and maybe a gentle cleaning with distilled water on a cloth would be useful, particularly in dusty, dirty, or just hot and insect-attracting climates.  You might be a bit more specific though, or we're guessing at what you really mean. Many of us buy canvas or boards which are ready-primed with acrylic - or Ampersand boards - or a variety of others, and just paint on them.  For most of us, this is safe enough, but you'd always want to buy the best you can get, and not cheap canvas or boards from stationery chains.  You're presumably starting with raw canvas and then preparing it, though - I'm not at all sure that your method is the best way of doing so.  Perhaps take a look at the Natural Pigments website, or buy Virgil Elliott's Traditional Oil Paint book and see how their recommendations compare with yours.  
‘Anyone looking for a tutorial is more likely find it there than within a dynamic forum where posts are pushed down the page with each new entry.’ I’m still looking for this ‘dynamic forum’… Sound advice from Robert, all of which I concur!
"Dynamic" = Characterized by constant change, activity, or progress. ie each new post pushes previous posts down, and eventually, OFF the currently visible page, thereby making them not immediately visible. I was not implying any level of interest or excitement.

I wash the canvas for dust accumulation after the oil coat is completely dry Sir. I think I did not convey it properly. I use thick layers of oil paint on my canvas sir, sometime I keep relief too. It works fine for me. By wash I mean, before I would start the painting, the canvas is still fresh with one thick coat of oil paint (not white color). White is not a preferred reference color to start a painting with. I just wash the canvas with water, keeping the canvas right under the tap, allow the water flow with small amount of water flowing on the canvas. Then I wipe the water with banian cloth, then allow it to dry for a few minutes, then dust the banian cloth bobble on the canvas. I have been doing this for years. A lot of paint on the canvas makes the painting look good. You should try it once sir.  Attached above is one of my recent paintings.

We all perhaps have different approaches to oil painting, but I still don’t think that applying a thick coat of oil paint over the primer or gesso is a good idea… or indeed necessary. I wouldn’t recommend it! More recently I’ve been applying a thicker mix of acrylic gesso mixed with chalk dust, two coats of this gives me a good reasonably textured thick surface to work on - followed by a thin translucent coat of a mid-toned oil paint or even acrylic as my ground.

Going back to the ‘techniques’ section on the forum, these are added by the online editor (not by members), and have generally been extracted from (vetted) articles written in both The Artist or Leisure Painter, or Dawn’s e-shots which she posts each month. I have contributed to a fair few articles on this section  myself, with hopefully accurate and useful information.

Thanks for the useful information! I believe that such lessons and guides are very useful for every student. After all, it can be complicated to find high-quality educational material or online services with which you can increase your intellectual level. That is why I recommend young people use educational platforms such as https://assignmentbro.com/ca/ so that they do not have problems doing homework. At one time, I turned to such a service due to a lack of time to complete history work. And I was pleased with the result.
