Here is the pattern, as promised:
This scarf knits up very quickly! It requires only one ball of worsted weight yarn (edit: I used Patons Classic Merino) and the 4-row lace pattern is easy to memorize. In order for the lace pattern to “fall” the same way on either side of the neck, I knitted the scarf in two pieces. The seed stitch border makes it difficult to graft the pieces together seamlessly, and I don’t think it’s necessary. Just bind off each piece and sew them together … that part will always be at the back of the neck anyway!
