An illustrated conference paper, first presented at the 2008 ALHFAM conference in Ottawa and revised in 2022. It surveys lace types (bobbin, needle, tambour, knitted and crocheted, and mixed techniques) and asks how lacemakers can stay faithful to both their craft and historical accuracy in living history museums. It tells the story of Margaret Weir (1808-1895), a Scottish tambour lacemaker who emigrated to St. Marys, Ontario, and covers early lacemaking in French Canada and American lace history, including Ipswich. It closes with practical suggestions for museum interpretation and costuming, plus references.
