My mom got me the completely awesome book Handkerchiefs: A Collector’s Guide for my birthday. The most prolific and well-known designer in the handkerchief world appears to be Tammis Keefe. I couldn’t find out much about her, except that she died too young, at age 40. She also designed other linens and maybe some fabric too. She sometimes went under the pseudonym Peg Thomas, but I don’t know why — maybe to flout some contractual obligations.
