When I travel around, one item I like to have with me is a towel as it has many uses.
Protection
At times, I am given electronics to repair without advance notice so make sure that it does not get scratched on the way to the office for repairs, I carefully wrap it with the towel.
Draft
Sometimes, there is a cold draft that comes in from under doors and with a towel, I can have the air blocked off thus keeping the room to a comfortable temperature. Also, if I need to utilize a space heater, it will reach the set temperature faster and do less work as it is not fighting against the incoming air.
Light
As with the draft, light can enter through the crevices around the door and the towel can help reduce the intensity.
Odor
Keep odors from entering from the hallway outside your door by using a towel as a barrier.
