You caught me, I'm an art addict as well ;) or atleast as much of one as I can be as a poor teenager with no free time.
My favorite thing to do is Mixed Media art. I work with melted crayons, india ink, oil ink (one of my favorites), newspaper, acrylics, markers, charcoal, graphite, watercolors, crushed glass, paper meche, you name it.
picky about my art supplies though. I'm normally a very laid back person and few things bother me, but if someone messes with my art supplies I'll turn into a ball of fire in seconds. My favorite ink pens are Pentels, but unfortunately they're $60 for a box of 33 and most of mine have run out. I also love squirrel and camel hair brushes for painting and GOLDEN acrylics.
I have an entire closet full of different paints, canvasses, and pencils...I think that last time I checked I had 104 pencils of varying size, material, and grade. My favorite are the cherry wood pencil though. They're so soft!
My most recent mural, the biggest that I've done (9x12) and my first commission. I'm only 16 so I have a ways to go, but it turned out pretty good! The water alone took 13 hours. The rest took me about 8 hours.
My entire wall is full of paintings and sketches too xD you can definitely tell what I enjoy doing in my spare time when you walk into my room!
