It adds a nice touch to a missions conference to have the national flag of each of the countries represented. Some churches have flags from all the countries where they help support mission work with special display of the flags of the nation present at the conference.
We usually include a flag ceremony where we have the children of the church march in one by one carrying the flags we wish to display at that conference. As they march in, a narator reads a few comments about the coutnry represented, who we have visting or help support from that county, and a sentence or two about the work they do. Soon I will post an example of the comments.
One great source of international flags (12 by 18 inch) on a stick is The American Flag Store. I have no financial interest in this company, but have just found it a great source of flags if you do not already have such a source.
