I filled up two sketchbooks so far this year (well, the first one I started in September), and am currently on my third one. It's a fancy schmancy Baron Fig I got from the Artsnacks studio collection in 2014. I've been putting off using it, because I have this issue about using pretty notebooks. I think I'm going to "ruin" them even though, you know, you're supposed to put shit in them. Same goes for this Simpsons Moleskine my friend got me about a year or so ago. Been thinking about writing ideas and such in it, but I never finish journals or idea books or whatever. I think the last time I finished a notebook as a journal in its entirety was when I was 16. I still have it and should probably consider destroying it. I also have issues writing certain things down, because I don't want people to read them ever and I have super paranoid thoughts about people going through my shit and reading everything... which is funny, because even I don't want to re-read some of my shit.
Been doing all kinds of crap like this in my sketchbook so far. After all these years, I'm still trying to think of a series, but think I am closer than ever. Since I haven't actually started on it, it's still a concept that I won't really share until I have something to show. Maybe I'll get started on that now.
