I remember a while back that I saw something that was cross between the two and I was hoping someone could help me find it.

Was it a one shot? I remember one that was a oneshot, though the title eludes me now. There was also this really old one that was a literal crossover that involved characters from both works, though I don't remember the title of that one, it was ages ago.

There was a story on FFnet called Labyrinth by Blackvid that was a retelling of the Labyrinth using the Inuyasha characters.
Not sure if it's the one you mean but I hope this helps!

Based on the movie "Labyrinth", after five days of searching for her brother in the Labyrinth, Kagome finds herself completely exhausted and overwhelmed by what she now has to do. She must call Sesshomaru and trade herself to him in her brothers place. The result is a delicious one-shot where time stands still and the need for physical pleasure is put on hold only by the need for sleep. This story is basically set in the movie but with different dialogue, and some different scenes from the original movie. Those of you who don’t know the movie “Labyrinth” you might find yourself having a bit of trouble following along.

Thank you guys! I'm pretty sure it used the characters as labyrinth characters instead of mixing them together.
