Sixth volume of an album of crochet patterns for antique Irish lace, written in French by Madame Hardouin and published for the Manufacture Parisienne des Cotons L.V. et M.F.A. It gives row-by-row instructions for series of motifs (stars, small motifs, arabesques, combinations), each followed by photographs of the finished motifs and of assembled pieces such as a child's collar, an insertion (empiècement), a lace edging, a baby bonnet (béguin), a berthe and a plastron. It also explains how to join motifs with the various net grounds (réseau), the picot edging and the ball picot (picot-boule). Patterns are worked in M.F.A. Irish thread, with recommended sizes given.
