Human Factors
I was the X FA and I disarmed my door; but forgot at first to move my door flag to the disarmed position; I gave the Gate agent a thumbs up; and when she didn't move; I realized my mistake; moved the flag to the correct position; gave a thumbs up and then we opened the L1 door. Triple check myself before giving a thumbs up! I was concerned about getting my face mask on for door opening and deplaning and I allowed this to interfere with my usual focus. In the future I will put this on after the door is opened since I can't wear the mask and  use the intercom to call to the back.
Flight Attendant reported initially forgetting to move the door flag to the disarmed position due distraction from putting a mask on to avoid COVID-19 exposure.
