www.watchawear.com is a good source to upload and download watch faces, watch hands and backgrounds for Face and WatchMaker.
One thing to watch out with facerepo is that you have to check the icon on the face listing to make sure it's compatible with Facer and not just Watchmaker. I got bitten by that a few times and eventually ended up just grabbing Watchmaker as well.
Facer definitely looks interesting: I'm amazed by how many custom watch faces there are available for Android Wear.
IT WON'T WORK I DOWNLOADED EVERYTHING I DID EVERYTHING AND THE WATCH FACE SHOWS UP ON FACE BUT WHEN I TRY TO GET IT TO MY WATCH IT DOESN'T WORK WHY ISN'T IT WORKING I DID EVERYTHING. I'M ABOUT TO FREAK OUTDjz
My situation is the same as yours....
