I found a tiny bit of possibly printed fabric from medieval Russia in an article in ATN 58, bringing the total of finds I have seen to 4. This is blue green and yellow on a tan or other light colored wool tabby, and is described as painted, technique unknown. The various pieces are reconstructed as part of an applied band on another garment, complete with contrasting red wool stitching. The finds come from near Lake Ladoga, and are dated 10-12th c.
I can’t tell what the pattern is, but am encouraged to find more painted/printed textiles in this place/time.
