I checked the icons in my "not yet" folder and surprisingly there where 200. All from various fandoms and stock. That's part of the problem - I tend to want uniform fandom posts... or at least for some of them.
And I probably should check if I truly didn't post them... for all I know I might already and just didn't move them out of the folder.
I'll skip scifieps20in20... I just really wanted to do Beast Below :D I might skip hp20in20 as well, limiting it to just fandom20in20 and season20in20 :D
