How Old is knitting in Great Britian?

Recent scholarship on has shown very a very high level of knitting skill in Estonia in the 13th century ( a study of a 13th-century votic knit fragment by Anneke Lyffland) but what about Great Britain?

See The Origins of Knitted Fabrics by Braham Norwick for a cogent argument that the Irish knew about knitting in the 8th century. He goes on to layout similar evidence for the knowledge of knitting in Scotland in the 8th to 9th century.

Worth finding and reading.
