Waistlines


Waistline treatments include casings and waistbands.

Closed Casings


The closed casing is made by folding and pressing the garment edge twice. The first turn is 5 mm to hide the raw edge and the second turn is the width of the elastic plus 2 mm. The casing is sewn at the edge of the fold, leaving 1.5 cm open. This temporary hole allows the elastic to be inserted, fitted, and joined. If the elastic lays flat and fits well, the casing hole is then sewn closed.

Standards for Evaluating a Casing


  1. The casing has two rows of stitching — one at the upper edge and one at the lower edge.
  2. The sewn lines are parallel.
  3. The casing is the correct width for the enclosed elastic.
  4. The casing is folded twice so no raw edge is exposed or the outer edge has been serged then folded and topstitched.
  5. The elastic is flat.
  6. The casing has been closed by stitching in a neat and durable way.
  7. The garment was seamed into a tube, and seams were finished and pressed before the casing was made.

Straight Waistbands


Straight waistbands are cut on the lengthwise grain and often interfaced for maximum stability. The finished waistband is folded, therefore reducing width of waistband by half. The finished width of a waistband ranges in width from 4 to 5 cm for maximum comfort.

The overlap portion may end flush with the zipper or it may overlap an additional 5 cm. The underlap portion might extend 5 to 8 cm. The choice is determined by the sewer.

Standards for Evaluating Waistbands

  1. The application is smooth and even.
  2. The waistband is smooth and flat.
  3. The waistband has been interfaced to prevent rolling and stretching.
  4. Both overlap and underlap are neatly finished.
  5. Any visible stitching is neatly done in matching color.
