In New York City in the 1930s, Mergentime worked with some of the best-known designers of the day, including Donald Deskey, Russel Wright, and Frederick Kiesler.
[3][4] In the late 1920s and early 1930s Mergentime, unable to find the types of table linens she wanted, set out to fill this niche by becoming a textile designer.
[11] Beginning in 1934, Mergentime focused her talent on producing table linens sold at Macy's and Lord & Taylor in New York, as well as at department stores throughout America.
Dorothy Liebes, at the time creative director of Goodall Decorative Fabrics, commissioned Mergentime in the late 1930s to create a collection for the firm.
In 1940, Mergentime worked with Russel Wright on his American Way campaign to promote household objects by the nation's artists that were sold at stores around the country.
