Fabric Notes
The Waist Cincher requires specialty fabrics: cotton coutil and heavyweight power net are required, and recommended fabric sources are included in the instructions booklet. If desired, a medium-weight woven may be used as a fashion fabric, in addition to the coutil and power net. Fashion fabric recommendations include: silk taffeta, dupioni, satin, and shantung; cotton broadcloth and sateen; or a natural-fiber brocade.
Recommended fabrics for the Petticoat include: lightweight cottons like batiste, lawn, and voile; rayon challis; and silk crepe de chine or charmeuse for the petticoat yoke. For the tiers of the petticoat, we recommend lightweight-wovens that will be soft against your skin like silk or synthetic organza or organdy. Chiffon can also be used, but it will create a softer petticoat with less structure.
Waist Cincher Supplies
- Coutil fabric
- Heavyweight power net fabric
- Fashion fabric (optional)
- Thread to match
- Eight 7-1/2 in (19 cm) lengths of 1/4-in-wide (6 mm) flat steel boning
- 2 yards (1.8 m) of 1/4-in-wide (6 mm) spiral steel boning
- Metal cutters and pliers
- Boning tips or Teflon tape
- 1 yard (0.9 m) of 3/8-in-wide (1 cm) boning casing/channeling
- 1 yard (0.9 m) of 3/4-in-wide (1.9 cm) twill tape
- Twenty size 00 (5.1 mm) grommets and washers

PICOT ELASTIC NOTE: the plain, flat portion of the elastic (without the picots) should measure ¼-in-wide (6 mm). Different suppliers will measure and label their picot elastic differently. Before cutting your pattern pieces, compare your picot elastic width to what is recommended, measuring just the regular elastic portion (not including the picots). If your elastic is smaller or larger than ¼-in (6 mm), you will need to alter the upper and lower seam allowances of the Waist Cincher accordingly.
