I made the sweater with size 4 needles, but it could also be done with larger needles, and adjusting the pattern with less repeats of certain designs. Definitely do a swatch first to determine your gauge and how that will work with the number of stitches. On the web page you will find a chart, but if you e-mail me at dmarty@telus.net, I can send you the Excel file that I worked from, and that you are free to alter.
