This is a practical guide to lace identification and technical variations, which also covers care and preservation. The distinctions between bobbin and needle laces and other techniques are shown, as are comparisons with machine laces which often cause confusion. A particular feature is the numbered key, a systematic method of arriving at the identity of the lace by means of the techniques used. Antique lace yarns are studied. A section on lace care deals with handling, washing, storage, display and presentation.
