A French-language technical manual on Cluny bobbin lace (continuous-thread laces) by Madame L. Paulis, published in Brussels in 1921 for Les Amies de la Dentelle. It covers the technical resources of Cluny lace (braids, crossings, picots, point d'esprit, toilé, twisted passes, spiders), then analyzes antique laces by element (decorated lines and crossings, circular motifs, festoons). Further parts treat design and composition, making the pricking pattern, and motifs worked on a movable pillow for insertion. It is illustrated with many thread-path diagrams and a few photographs of lace.
