A 2003 web article by Brian Lemin on the use of pewter as decoration on bone and wooden lace bobbins. It covers the composition of pewter, how makers cast it into grooves, and why old pewter inlay swells and crumbles (tin pest). It also describes the standard East Midland inlay designs (butterfly, leopard, tiger, trailer, compound, spiral), South Bucks gingles, and comments on individual makers such as Jesse Compton and Bobbin Brown.
