Door Sign: If you tell me I cannot do evangelism because I cannot go anywhere then this is for you.  You can put a sign on your door that is as artistic as you like.  You can print out a gospel message and put it on your door.  You can put a link to a website on your door like NeedGod.com or changeyourcampus.com/God.

You could laminate the paper so that it will not be ruined by the weather.  You can use packing tape to laminate the paper.  That is what I use to laminate my huge custom signs I make with permanent markers.

Magnetic Tract Holder: You could get a magnetic business card holder and put it on your door and put tracts in it.

Box of Evangelistic Material: I have seen people put out boxes with notes on them that said please take me.  The box could have DVD’s, books or anything evangelistic in the box.
