This is a variation published with permission of Alyssa McFarland’s pattern Sleeveheart, from her site Coiled to Spring and available as a free Ravelry download. I LOVE this pattern and making it got me started on an obsession with half-pi and pi shawls. I wondered how the pattern would look in a self-striping yarn like Noro and made a few modifications for a sock weight yarn (original sleeveheart is done in dk weight)
It’s a classic pattern -- once you make one, you’ll be hooked -- make the original and try the variation!
