Narrative:

I was parked at FBO tus. I asked for taxi for takeoff. They gave me taxi taxiway 7 to runway 11R. I taxied straight ahead to runway 11R which I thought was taxiway 7 and turned left. I noticed an aircraft above me about 50 ft I thought he was taking off over me and I called ground control and asked if I was on the runway. He didn't answer so I called him again. He told me yes and to continue on to next taxiway to left and hold behind lines. I did so. He asked me if I didn't see hold lines on taxiway before I got on the runway and I said no. After I took off they told me to call the supervisor when I landed. I called him and said I was very sorry. I said I thought they should have a taxiway sign to identify taxiway 7 and a runway sign to show 11R-29L. I told him after takeoff I saw a hold line on taxiway in dark red and a black repair line on the taxiway before the runway.
