I make a few charity quilts each year, usually lap quilts or baby quilts. I welcome the opportunity to share, and it gives me some valuable practice time. The guild I belong to is a charitable organization, and contributing in this way is encouraged but never required or demanded. Some people contribute by donating the fabric and other materials, some are organizers, and others donate their time in sorting the fabrics and putting together kits. There is a great need for quilts for homeless shelters, victims of domestic violence, veteran's hospitals, a camp for special needs kids, etc..
