There are two schools of thought on the finish/don't finish question. Some people think that if you or someone else finishes the quilt, it diminishes the value because it's no longer a "pure" heirloom. Others feel that the top was originally intended to be used or displayed so it really needs to be finished to fulfill its purpose. Do what you feel is right for your particular quilt or family. If you think the quiltmaker would want you to finish her work so that it can be enjoyed as a finished product, by all means do so if you feel you or someone else can do it justice. If the quilt top is in a very fragile state, you may not want have it quilted but only preserved in its current state. Do what makes you happiest and don't worry about what someone else thinks is "right". We'd love to see pictures, too!
