Hullo, AuraSky! soo... I believe that you have to put the markings files into your Feralheart textures folder! You can get there by going to your Feralheart folder, then to your media folder, then to your textures folder.(:
but, it's been a very long time since I had to download markings, so don't take my word for it, but it may work if I remember correctly! Best of luck!
