I've come across a charity that's a good place to spend your time, extra fabric and help yourself feel warm and fuzzy inside.
This is an inter-denominational effort to provide simple, pretty dresses for children in Africa. They provide the patterns, all information on shipping and have answers for any questions you might have. They've also gotten the support of Sewing with Nancy.
The dresses are simple and easy to decorate, and can make a big difference to the children there.
They're also a good thing to do with children who want to learn to sew. They can learn some basic skills and know they're making clothes for children who might not otherwise have anything.
