That's more than enough I thought when I started the Skater Overtop from "Knitting Classic Style" by Véronik with the Black Bunny Fiber Merino Lace. I was right. Barely. Of the former existing two swatches I have one left because I had to rip one out to finish the last row and bind-off of the neckline.
It's the story of the knitter who had an uneasy sense of not having enough yarn but who kept knitting and knitting....well, it paid off. Phew. Dodged that one.
