Lovely yarn to work with...Banff 100% Merino Wool from Canada. Machine washable bulky weight. Worked top down starting with a square. Size 10.5 needles...double points because the smaller circulars are a little less fun to work with :-) I used one ball with a couple of yards left over.

Color Denim Heather - 100g - 86 yds. Yarn available here.
