Ditzy print, ditsy print
A ditsy print is a very small scale all-over pattern with a random look, not linear or geometric. Flowers are often depicted, but are not exclusively used.
American textile manufacturers, particularly from the 1920s through 40s, mass-produced cotton ditsies, dumb-dumbs and bread-and-butters. These were popular and inexpensive, and the names refer to their innocuousness, as well as their saleability.
