This area is for newcomers to the oil painting art. I will add suggestions on equipment and even pointers on where to buy it and maybe a demo page. I have had some enquiries for such information. I am not a qualified teacher so it won't get to that stage. These are suggestions for beginning, you will naturally branch off from them after a try or two.
6b, 2b, hb, 2h to start
I have learned to draw with my paint brush as I paint the picture, after many years of painting. I do this by first drawing a simple sketch on the canvas as a reference as to size and position.
I drew many sketches with a pencil before I even started painting portraits in oils.
My first lessons in class were to draw a sketch of a person in 10 seconds, and then in 30 seconds and then in 1 minute and after a couple of weeks I was allowed to make a pencil painting with detail and shading. I still draw in my sketch book and solve some compositional problems before starting the painting full size.
There are many. but I'll just mention a few to get started
Oil painters use long handled brushes
Hog hair makes a fine stiff brush usually for roughing in. 4 or 5 Sizes 2-12 are good and you can buy say a 2, 4, 6, 12 filberts and whatever quantity you can afford
no's 6 round, 2, 4, 6, 8, flats
Use artist grade or better paints only, the color content is better.
