I occasionally post on a blog at Jaime Cooper Gallery & Studio which is a resource for realist based classical art lessons for art teachers and art students.
Scroll down for supply lists.
Below are some suggested supply lists. I typically purchase supplies from Blick. I also purchase oil mediums from Natural Pigments. Beautiful palettes may be purchased from Turtlewood Palettes. I like Grumbacher and Winsor Newton oil paints, but that is because I started with them and am used to them. I find them a great balance between quality and price. Any professional artist grade paint will work. Do not use student or academic grade paint. It will cause more frustration than the money you may save is worth. Brushes are up to your personal preferences, but I list some of my favorites below for your reference.
Gamvar gloss varnish
Paper towels or rags
Easel (this one is a nice balance between sturdy and price)
Zinc or soft mixing white
Alizarin crimson permanent
Silver Grand Prix
Copy paper or sketchbook
Sanded pastel paper
(600 or 800 grit)
I prefer Tombow, but any artist quality pencils will do. It is not necessary to get a full set. Something like a 4H, 2H, HB, 2B, and 3B will do.
I use terra cotta and black most often
Pitt pastel pencils
I use sanguine most often
White chalk pencil
both Pitt and Generals make them
Medium grit sandpaper
