Update from LDFA (Little Dresses for Africa) website:
If anyone is interested, they need britches for boys (not as fun to make but needed). Any simple pattern will do.
Also they are in need of small dresses for girls under 2 and larger girls (formerly size 12). If you are making a dress for a larger girl please take into consideration the hips and bust area. They have found that king size pillowcases are too narrow thru the hips and bust.
There is also another pattern to try using a T-shirt and adding a skirt also suggestions for making shorts out of holey jeans (pants with holes as opposed to holy as in religion)
