Related subreddits

Hi folks,

I'm slowly working on our wiki page and am currently organizing related craft subreddits, but I'm sure I've missed some. Could you comment subs that you know of that aren't listed? So far, I've limited subs to those that:
- are active (a post within the last month)
- have more than 1000+ subscribers (although there are a few very, very active subs I included that have about 650+)
- aren't shilling for a user/company

I'll leave a comment for each section, so please comment subs I may have missed underneath the correct section. I also am not set on the headers for each section, so chime in with your thoughts please.
