✿ Dainty, delicate and full of ruffles

One of my favorites! This knit onesie is perfect for summer or a photo session. It’s dainty, delicate and, best of all, it has ruffles.

It’s knit flat on straight needles, with a larger needle for the ruffles and an optional ribbon tie at the middle.


✨ What makes it work

  • Ruffles. Butterfly ruffles worked on a larger needle.
  • Straight needles. No circulars needed.
  • Optional ribbon tie. A sweet finishing touch at the middle.
  • Easy level. Simple shaping with a big payoff.

✂️ What you’ll need

  • Needles: US 7 (4.0mm) straight needles for the body · US 8 (5.0mm) straight needles for the ruffles
