/* Checks */
:Multiple fragments of the same cloth in four layers was found in grave VI/1930. This cloth is a fine woollen chevron twill with a checker pattern formed by two light, probably linen, threads in the warp and weft. [HAGG 1991: p.241]
*Birka, Sweden: 1 example of a linen tabby fragment was found in Grave 757 where both in the warp and the weft a white then red thread followed every 5-6 blue threads.The cloth had about 20 threads per cm, so the checks were quite small. [GEIJER 1938: p.15]
