We call this lace, “When Scientists Marry!” If Gertrude Belle Elion (renowned research scientist in chemistry) had ever decided to tie the knot, her gown would have been trimmed with this enchanting Chantilly lace. This is a 2 1/2″ wide ivory Chantilly lace in an oh-so-scientific pattern of double helixes, on a loose netting background and framed by a wee picot edge.
