American Patchwork & Quilting One Million Pillowcase Challenge is a great charity challenge!! They have hit the 500k mark, but that took two yrs. they have several patterns for making pillowcases from basic to quilted, and they go to women's shelters, children's hospitals, The Shriners, Hospice centers, etc. there is a list, but you could coordinate with your LQS or the point of reference for your area and they might lend an idea.
