A short essay by Brian Lemin on how broken lace bobbins were repaired by bobbin makers and lacemakers. It covers the cricket bat splice for broken necks, riveting of loose bone bitting, repairs to chipped short necks (heads) with sealing wax, buttons or beads, problems with pewter inlay, and fixes for spangle fastenings. The author also discusses which splices may be original construction rather than repairs, and notes how little evidence of repair survives in collections.
