The pattern was suggested by Freda on my "Crochet Weave" post.
I have copied this from Big Book of Knitting Stitch Patterns
Publisher: Sterling Publishing Co., 2005
Another suggestion is that the picture depicts "Railroad Knitting" which is a synonym for Tunisian crochet/knitting. Here is an example of a simple Tunisian stitch pattern and an instructional video.
Thanks for all of your suggestions!
