Lampas could be defined as twill weave with a supplementary weft, for brevity’s sake we will leave this here. To the experienced weaver this definition could include any number of weaves which were not lampas. A preemptive example of lampas was this lampas silk from Southeast Spain, the Clothworkers’ Center Catalogue 1312-1864. There were a number of repeated designs incorporated into this cloth. The designs measured as follows; green design 4.5 inches, blue square design 7 inches by 7 inches, blue round design 7 inches, grey/silver 4.5 inches. This cloth illustrated another type of cloth available to European consumers. The Clothworkers’ Centre has been conserving a number of lampas woven cloths, which would indicate lampas was a staple in the wealthy home.
