I work with mainly digital mediums. I am very impatient and if I screw one thing up I really hate myself until I fix it. I also get really bored if I have to sit down and work on one thing for a while, digital seems to keep my interest because you can change what you do as you work with it, I want that sprinkle green and that heart orange.
I started with photo-manipulation, or rather, laying textures and brushes over another image and playing with the layer properties. It can be an effective tool when used properly. When I found vector art I realized photo-manipulation was really not for me anymore. I started free hand, then traced from photographs and I have moved into making vectors off of drawings. I'm still having that from drawing to vector problem with a lot of my work.
I find that I seem to spark more creative energy when I switch mediums. I'm currently taking a traditional drawing class in school and we used conte crayons which are absolutely one of my new favorites. I also applied the ideas from that to working with highlighter and thin sharpies. It always opens something artistically for me when I start a new medium or when I see something in a new medium I haven't yet explored.
I think though that my favorite medium by far is the more physical mediums like arts and crafts. I am completely serious, I love paper mache, and designing things with cut paper. I like the shapes and textures found in everyday things like bottles and flowers.It's all very enticing to me.
