Go up the stairs and go straight towards the decorative rug. Walk off the rug and stop before you go down the stairs.
Go up the stiars, to the landing up the riest of the stairs, and forward over the rug, stopping at the next set of stairs.
Turn around, and head up the stairs. Go all the way to the top. Walk straight ahead to the rug. When you've walked the length of the rug, stop and wait there.
