Kris, they are Acrylic and inks, mostly acrylics. I love working with acrylics they do dry fast and I can add layers sooner. If I want it wet longer I mist with water from a spray bottle.
I love oils too, just haven't played there in a while. I bought new paints in oils to get back to that medium, so you can expect those in a few weeks:) I have done charcoal drawing too and enjoyed that.
So many fun things to do, never enough time!
The pastels can be sealed to preserve them, probably the same spray I use on my acrylics,it is clear acrylic spray in either Matte or Satin, I change depending on the piece.
I have never had art lessons, I am self taught, but watercolors scare me so I plan to take a beginners work shop in the fall. If it works for me, I can go on alone if I get some simple basic techniques.( I may be over confident:)
