Here are a couple paragraphs that will take you step by step from the cat/earring action to the room where the kohl/makeup is located. Seems to me that the kohl looked like a black lump...not sure now...

Place the bowl of milk on the mat beside the two sticks. The cat will come into the room. Look at the cat and take the earring its wearing. Look up to the right of the cat and use the earring on the outline of a niche, about midway up the wall. The door of the niche will open to reveal a letter and an ivory square; a Senet piece.
Turn and exit the room. Go forward. Turn and go forward twice. Turn right, go forward. Turn left, forward and enter the room with the closed door. Go to the room on your right where you see two baskets and a lamp. Find the necklace and the wig. Go to the next room to the right of this one and find a tunic. It will disappear, meaning you are wearing it. Then go to the next room to the right of this one, a bathroom, and find the mirror and the kohl (makeup). Use the mirror. Put on the wig by using it on your face in the mirror. Use the kohl the same way. Turn around and go out to the woman servant standing in the center room.
