Russian lace is a bobbin tape lace. The tape is made with bobbins at the same time as the rest of the lace, curving back on itself, and joined using a crochet hook. It was made in Russia, but similar laces made elsewhere are also called Russian lace.
The designs of Russian lace are of abstract form. The narrow tapes or trails follow a maze-like path through deep scallops to merge again and wander into the next. Examples of many regional styles and examples are available in scholarly works, and instructional materials have also been published with typical stitches.
