Grandma Harriet Carpenter's designs were originals. Perhaps Stars and Comet was inspired by the Great Comet of 1882.  A mystery, however exists regarding four Rainbow quilts in the IQM Collection.  One is a recent gift from one of Grandma’s Harriet Carpenter’s descendants. The other three in the James Collection are attributed to Susan Frey Habecker and Mabel Mae Brubaker. Harriet Carpenter’s mother in law was a Habecker and both they and the Brubakers are found in the same neighborhood. The identical format – including elaborate quiting – indicates they were made from the same pattern, however, to date no link has been proven.
