So I've come across multiple polls asking, "Have you ever suggested a Daily Deviation?" Sadly the most frequently chosen option was, "I don't know how to go about it." Not yes, not no: the uncertainty of the process.
I will make this as easy as possible.
1. Go here, and note one of the Community Volunteers in charge of the category of art you're suggesting. If you'd like you can also favorite this journal for reference.
The note should be as such:
Title:
DD Suggestion
Body:
:thumbxxxxxxx: (found to the right of the deviation, underneath the groups).
A reason why (is preferable but not necessary).
Tips


Now go forth & suggest.
