Cary Karp demonstrates some potential connections between the two fiber arts. According to Karp, "Knotting and tatting did appear sequentially in the historical record and can reasonably be regarded separately...the demarcation between the structures that characterise knotting, and the central elements of tatting, was not as clear cut as is often maintained." Tatting has been used in occupational therapy to keep convalescent patients' hands and minds active during recovery, as documented, for example, in Betty MacDonald's The Plague & I. Workshops and competitions in tatting continue to be available from lace guilds and organizations.
