The BBC Sherlock Valentine's Day Prompt-A-Thon

An annual prompt-centric event (run in January/February with posting the week of Valentine's Day) that shows love for our favorite ships (romantic and platonic) from BBC's Sherlock in celebration of Valentine's Day, Galentine's Day and Singles Awareness Day.

The BBC Sherlock Valentine's Day Prompt-A-Thon Info And Rules Post

This is going to be the permanent pinned post with the rules and info for the blog, and the AO3 collection link here will go to the main collection, not the ones for each individual year. I will post the link to that collection when the new event goes live.

INFO

The BBC Sherlock Valentine's Day Prompt-A-Thon is an annual fandom event for the BBC Sherlock fandom honoring the various romantic, platonic and familial relationships with fanworks inspired by any one of up to five prompts sent to the participants.

RULES

Any kind of fanwork you can think of is acceptable for this event: fanfic, fanart, fanvids, manipulations, gifsets (please make sure they are your gifs, though, and you’re not taking them from others without permission), meta, headcanons…anything you can think of that would celebrate your favorite BBC Sherlock ships/friendships/family relationships that would fit in with one of your prompts will be accepted with much pleasure. However, there are absolutely no AI works allowed.

Crossovers of all fandoms are welcome! This is not a strictly BBC Sherlock event. As long as a BBC Sherlock character is a main part of your fanwork, feel free to cross BBC Sherlock with any other show you like.

Be kind and respectful to everyone participating. We don’t want any wank because this is a week for sharing our love for these characters who all adore.

Any and all romantic ships are allowed. Het, femslash, poly…you ship it, we want to see it! We turn no one away. All ships are valid ships, including the Holmescest ones. And friendship and regular familial relationships are also much appreciated. Likewise, all takes on a character’s sexuality and gender are valid for this week as well. Not everyone shares the same headcanons but we should all be respectful of others.

If you post something you want seen in the general tag, please make sure one of your first five tags is “sherlock v day prompt a thon”. We will not be using secondary tags as we don’t want to clog the tags this round.

If you want your work to be reblogged on @hardlogicversusromanticwhimsy you must @ the blog somewhere in your post. I get alerts on the activity when the blog is mentioned and then I will know to go and save your post to the drafts to reblog when the round is over. I will still check the tag but there is no guarantee I will see your post unless you @ @hardlogicversusromanticwhimsy as well.

Also! Please remember to lift up and encourage your fellow BBC Sherlock fans when they post fanworks to the event. If there's something submitted you like, please reblog it so others can see it, and try to at least leave a kudos if it's on AO3 (if you can, though, comments are always much appreciated too!).

TIMELINE

January 1st: Prompt claiming begins February 7th: Posting to the AO3 collection and the Tumblr begin February 21st: Posting to the Tumblr ends (AO3 collection is open in perpetuity)

AO3 COLLECTION

There will be a collection, as per usual, which will be opened as soon as I make it for people to post their works. It will remain open for perpetuity as you are always allowed to answer these prompts even after the posting dates are officially over. You can find the main collection here.

Prompt Claiming For The 2026 BBC Sherlock Valentine's Day Prompt-A-Thon Is Open!

So I ended up being in a car accident in December as well as losing access to my old laptop that month, so I had to extend deadlines for a larger fandom event I run, and ended up not being able to focus on my two Sherlock-centric events fully. As a result the other event just finished and, as I got a new laptop, I was able to finally regather most of my prompts and can now open the event!

As a result of the late start, posting for the 2026 round will go from February 7th to February 21st. The updated schedule and rules/FAQ for the event are up at https://www.tumblr.com/hardlogicversusromanticwhimsy/805336458211803136/the-bbc-sherlock-valentines-day-prompt-a-thon

Please message this blog (either via ask or DMs) with the blog you want your prompts sent to and whether there are any specific BBC Sherlock/BBC Sherlock crossover pairings you would like (if you do not provide pairings they will be generic sentence prompts).
