What should i put on a T-shirt to sell? It is to support my sister and I going on a mission trip to Haiti?

Hi! I teach Missions to the children at my church. The "theme" verse right now is

But you will receive power when the Holly Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the Earth. Acts 1:8

As we studies the above verse, what it is saying is be witnesses in your city/town (Jerusalem) and in your county (Judea) and state (Samaria) and to the ends of the Earth (spreading out over the Earth).

Another relevant verse, or verses rather, is The Great Commission

Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Matthew 28: 19-20

I think either of these verses would be great.

Other ideas for fundraising for your mission trip are:

sacrificing something you enjoy, and putting the money that would have been spent on it toward the trip. For instance, if you regularly go to the movies stay home instead and put the money that would have been spent on tickets and concessions toward the trip.

Babysit. Walk dogs. Wash cars. mow lawns. Shovel snow. etc.

Host a spaghetti supper at your church.

Send out sponsor letters (you can find samples online and customize them).

Host a yard sale.

etc.
