While I was poking about on http://caeranterth.northshield.org, which is the website for The Barony of Caer Anterth Mawr in the Kingdom of Northshield, I found a link to "Viking Embroidery Stitches and Motifs" by Þóra Sharptooth MKA Carolyn Priest-Dorma.
The images of the motifs are charming, and there's a nice discussion of Viking textiles, threads, and embroideries from tenth-century grave sites. I especially enjoyed reading about Viking ornamentation on seams.
The bibliography is an excellent resource for locating photographs of extant embroidery samples.
