Not using pattern for shawl size, but CO 152 for cowl size. Using Cat Bordhi moebius cast on. Reversible patterned lace should do well for moebius effect.
Did 1 1/5 repeats of pattern for a width I feel comfortable with.
Tried blocking with 2 tiles made into tube; it was too stretched and so too long. Re-wet and just left flat to dry pulled top-to-bottom to show the pattern and to make shorter circumference. End up with a nice size.
