A member of my Yahoo group and Ravelry was asking about TC with Peaches and Creme... a worsted/aran weight cotton yarn.
This is one project I used TC with a lacy open stitch Arrowhead Netting.
The pattern for this blanket is in the booklet: Arrowhead Netting, that includes instructions for one method for creating Round objects.
