I bought this precious skein of Malabrigo laceweight merino in New York and didn't want a yard of it to go to waste. And I've always wanted to try the Sunspots lace pattern from Barbara Walker's Third Treasury (pg. 151-153.) Match made in heaven.
For anyone interested in trying it, I cast on 63 stitches (5 pattern multiples) and did 15 repeats of the 24-row pattern, then continued the first six rows of the 16th repeat and cast off there. To make the tassels, I wrapped yarn width-wise around the Treasury book 20 times, making six tassels for each end of the scarf. I had just enough yarn left over to play Cat's Cradle. Edited to add: on US size 4 needles.
