As of recently I have been very much into art journals, and keeping mine up, and selling kits in my store, which if you are an artist/writer art journaling is amazing and awesome.
First what is an art journal??
Art journals generally combine visual journaling and writing. Every imaginable style, media and technique is used by art journalists. There are no rules!
An art journal is a visual diary, a place to play, experiment, imagine, remember, try new techniques, and to document your daily life, your ambitions, and your dreams. It is also a place to scream cry to lament to fantasize and to get in touch with your innermost self.
It is like journaling scrapbooking painting and college combined into one fantastic playful messy experience!
Now my tool that I use every time I journal?
Paint and paint brushes! I love love love paint, I love the messy feeling and the paint on my hands. Sometimes I find paint splotches in random places after I am done, I always laugh.
So my favorite tool right now, is my brushes, foam, small, big, wet, dry, new, old, BRUSHES.
This is just a tool that as an artist, I cannot do without. I buy them whenever they are on sale i just love having new brushes to use with all my paints.
