Although the so called ‘pan-Slavic’ colours – red, white, and blue – were introduced only in the 19th century, they were rather common and widely worn colours in the Middle Ages. Red dye was obtained from dried madder root, while blue from dried leaves of woad and later, indigo.
The pattern is inspired by zig-zags and diamond shapes typical of the Viking Age tablet weaving. It came out beautiful but hypnotizing, certainly not for shy ones! 🙂
