KNITTING INFORMATION


The small afghan in the photo was made with DK yarn. It could also be used as a shawl if it is made in lightweight yarn. A thicker yarn would make it larger.


It is not easy to adjust the size in any other way, except by adding an extra (plain) ring, or working fewer rings.


The pattern also includes instructions for making a circular afghan.
