I used the Wool of the Andes Worsted Yarn from knitpicks. It looks and feels thinner than any other worsted weight yarn I’ve worked with, so DK weight yarn may work well for this also.

If anyone has any questions, please ask! I’ve also posted a video tutorial showing how to increase and decrease with double knitting.
