I have a friend who spends a few months a year volunteering in Uganda. He helps distribute clean water systems and teaches the people there how to use them. He also helps do repair work on buildings and volunteers at the orphanage.
He put out an appeal on Facebook to his friends to collect dresses for the girls there. He said they have never owned a dress of their own.
I found this pattern (the Lillian Dress) on Nancy Zieman's website (linked above).
These are so much fun to sew; especially since my 3 daughters are grown and I'm not a grandma yet.
Here are two of the three I have sewn so far.
