Oil Pastels:
(this link has lots of links IN IT! check each one out)
(just a good forum in general for art questions)
Chalk Pastels:
(don't forget you can blend with brushes as well, specifically with FAN, FLAT, and ANGLE brushes. you can try both wet and dry finishes, but NOTE: wet pastels will act differently and move differently!! They will initially get DARKER, and--depending on the quality of the pastel--can turn "chalky" white after they dry, so test things out before you commit!!)
(just fun! for texture! :))
Colored Pencils:
(okay, YES, she IS selling prismacolor products, ignore this and watch her techniques and tool handling)
(this lady is also selling prismacolors, but she is very informative about tool handling and color blending, so worth watching.)
(with mineral spirits! fun technique!)
