I blog about....everything. anything interesting that I see or that happens around me, stuff I make, how I make stuff. I write diy tutorials for techniques I use, too.
I post process shots, make little videos. I write about my personal life, about my ideas, and about my art.
I just write about anything I think about. sometimes when I am hurting for ideas I interview other artists. I review movies, music, tv shows, art, craft, anything I find I have a strong opinion about. For some weird reason I've written about stephen king almost every time I have a flu or cold!
