📌 Supplies You’ll Need

Before you dive into sewing your Beau’ Petale Skirt, make sure you have the right tools and notions to achieve a polished, professional finish.

This pattern requires precision. Be prepared with the right tools:

✔ Stay Tape (1/4” or 1/2”) – DO NOT skip this! Use Nancy Zieman’s two-sided stay tape for shoulders, neckline, and armholes.
✔ Jersey Needle – Ensures smooth stitching on delicate knit fabrics.

🛠️ Tools:

✔ Walking Foot – Helps with knits that like to shift & stretch.
✔ 7.5 Inch Gingher Pinking Shears – If you’re working with linen blends, this prevents excessive fraying.
✔ Serger (Optional) – Not required, but highly recommended for a clean, professional finish.

⚠️ Plan Ahead: Cutting Out This Pattern Takes Time!
✔ Spiral pieces = extra cutting time. Cut them carefully at night, then sew the next morning.
✔ Print 18 pages. Tape them edge-to-edge, corner to corner for accuracy.

⚠️ Skill Level: Advanced

This isn’t your average sewing project. The Jonquille en Fleur Flutter Collar Shell is an advanced-level pattern for a reason—precision is everything.

✔ Challenging Neckline Construction – The flutter collar and curved edges demand accuracy in cutting, stabilizing, and sewing. Any misalignment throws off the entire design.

✔ Fabric Composition is Critical – Not all knits will work. The pattern requires specific weight and stretch to achieve the right drape, structure, and fit.
⚠️ Too stiff? The collar won’t flow.
⚠️ Too stretchy? The seams won’t hold their shape.

✔ Difficult-to-Handle Fabrics – Lightweight bamboo, linen knits, and slub jerseys can be slippery, prone to distortion, and fray easily.

✔ A Serger is Highly Recommended – While not required, finishing the delicate knit edges with a serger will give a cleaner, more durable result—especially around the neckline and armholes.

⚠️ ✔ Stay Tape is NON-NEGOTIABLE – To prevent stretching and gaping, you MUST use stay tape at the shoulders, neckline, and armholes.

💡 This pattern is for sewists who love a challenge—and love the payoff of a truly designer-quality result. Take your time, follow the fabric guidelines exactly, and you’ll create a stunning, high-end blouse that’s worth the effort. 🚀
