I belong to a group that is one of the "friendship" groups of my quilt guild. we do community service projects. Our main receivers are a medicaid nursing home, what used to be called an unwed mother group and a church related children's home. We make lap quilts for the nursing home, baby quilts for the mother's group and bed quilts for the children's home. We have several long arm owners who are members of the guild who do the large quilts.
For the lap quilts for the nursing home, we just quilt them. I usually do straight line quilting, as I have not yet learned to do free-motion quilting. My quilts keep the older folks warm just as well as the ones that are free-motioned. I make great "I Spy" quilts for the young ones.
Just play to your strengths. Just don't take on huge quilts. There are lots of needs for smaller quilts that don't require long arming.
