LOL--Thanks EC and AndesCat! Nice to know I got the details mixed up.

This may have been taken off the site, but here goes:

Inuyasha and Kikyou were killed in a car accident, and Kagome is left with Rin, her niece to raise. The Tashio family wants to get custody of Rin. Kagome is a gifted fabric artist, and she is secretly Dear Scarlett, the sex advice columnist for the love lorn.

There is much more, but this should be enough to ID. I think the author was Runningwithscissors or Danceswithscissors.

Thanks!

It's Dancing with Scissors. It's on Dokuga.

EDIT BY WICCAN ON VACATION: RATED MA, NO YIMs!!

That wasn't the author's name you remembered it was the story title.

Complete! Thank you for your patience and support. Kagome's niece, Rin, is left orphaned by a tragic car wreck, leaving Kagome to raise her alone. Or so she thought...help comes from an unexpected source, Sesshoumaru. The only problem is that they can't stand each other. Will they be able to act like adults for the sake of their niece...and maybe find love in the process?
