Skill Level & Notes 💡
- Skill Level: Intermediate. You must be comfortable with top-down raglan shaping, joining new stitches, and maintaining a multi-row shell pattern repeat.
- Construction: The entire dress is worked seamlessly from the top-down, joining at the end of each round. There is a small back neck slit for easier dressing.
- Skirt Repeat: The Large Fan Shell pattern requires a stitch count that is a multiple of 6 stitches. Adjustments are made in the yoke separation round.
- Chains: The starting chain (ch 2) at the beginning of HDC rounds always counts as the first HDC unless noted otherwise.

Assembly and Final Touches 🫧
- Weave in all ends securely using the tapestry needle.
- Attach Bow: Securely tie the patterned ribbon into a small bow and sew it neatly onto the Aqua Teal yoke, slightly off-center below the neckline, as pictured.
- Blocking: Gently wet or steam block the dress. Pin the yoke to keep it flat and pin the points of the LFS shells to fully open the lace pattern and maximize the flare and drape of the skirt.
