Construction Notes

  • The Swallowtail V-neck is a set-in sleeve tee, featuring a fluttery hem paired with an understated, tailored upper torso. Worked bottom up, in the round, and then split front and back. Sleeves are worked separately in the round, then shoulders are seamed and sleeves inserted with mattress stitch.

  • For confident intermediate to advanced knitters who are comfortable with shaping and lace work.

  • All bind-offs should be worked with Sloped Bind-Off.
