would you want your quilt to be tossed in a dumpster because it was inappropriate to the receiver.
Lets respect the work of the church. They don't go in preaching but "doing good works" Religious oriented quilts have no place on the mission field unless they are specifically asked for. I have lived overseas and and well acquaited with the work of any church's mission work. Be safe and know the quilt will cover a body on a cold night It is possible the symbol being used may have other meanings to a different culture.
