I participated in a project and we made 115 youth-size quilts in six months for an orphanage in Kenya. We had probably 12 people working on the project, some more serious than others. Most of our quilts were pieced, which takes more time than solid panels. It is doable, but it really takes a concentrated effort. As I figure it, you will need to make 13 a month to be finished on time. Perhaps you could recruit others to help?
It is a great feeling to see pictures of the recipients who had nothing to call their own with their quilts. Good luck!
