I was originally designing this just for myself, but some people expressed interest in having one for themselves, so here you go! (I really do not think I’m any good at graphic design/photoshop, though, so lower your expectations accordingly.)
You can download the files here from my dropbox, or, if you’re lazy like me, you can order a printed version here. (I haven’t used this website before, but the reviews were good. I’ve ordered one for myself, and I’ll post pictures when it arrives if you want to wait and see how the quality is.) Enjoy!
