The Demorests faced increasing competition from other pattern companies, such as Butterick, which began to gain market share. This competition led to financial challenges for the Demorests.

Due to financial difficulties, the Demorests were forced to sell their business. The exact date and circumstances of the sale are not fully documented.

After selling the business, Ellen Demorest largely retreated from the public eye. Information about her activities during this period is limited.

Ellen Louise Demorest died on August 10, 1898. The location and circumstances of her death require further investigation.
