Our group -Knox Frox--sends the dresses & pants direct with mission groups. One literacy group going to Africa takes the suitcase on plane but we pay for the cost of the luggage . Luggage money came because we used extra
fabric and sewed placemats / pot holders / aprons etc which we sold to make a luggage money fund. Usually it has cost us $ 40. a suitcase and we get a big number in it depending on size. Last time I donated one of my older suitacases too.
Suggest you check around for the correct charity as I started this group and I said I didn't want them sitting in a container on a dock or sold at some yard sale in other countries.
