At Old World Designs, we often get questions about stitches. The most common questions are 1) how to basketweave, 2) how to use a laying tool, and 3) how to do turkey work. If you live nearby, come on in and ask, or even better, sign up for a class. YouTube is also a great source of instructional videos, and we've provided some of our favorites here, along with additional stitch instruction videos from our team.
Another helpful resource is our FIBER CHART, which gives guidelines for the number of ply to use of a given thread based on canvas mesh size.
