Assembly

(Shortened version – full instructions included in PDF)

  1. Assemble Front
    Fold the top piece and sew it to the front center and lining layers.

  2. Prepare Side Straps
    Cut or use pattern-included strap pieces. Each strap is 2½” wide and stretches along the length.

  3. Attach Straps to Front
    Stay-stitch folded straps to the front triangle sides, wrong sides facing out. Leave extra length unsewn at the ends.

  4. Close Strap Ends
    Fold remaining strap sections, sew closed, and turn right side out.

  5. Form Leg Openings
    Straight stitch strap ends together on each side to create leg holes. Leave at least ¼” seam allowance.

  6. Finish Strap Ends
    Fold seam allowances inward and topstitch to hide raw edges.

  7. Secure Leg Openings
    Sew around leg openings using a stretch stitch to fully enclose seams.

  8. Finish Back Seam
    Overlap back pieces and sew center back seam.
    Standard back length is 3½”, adjust longer for larger sizes if desired.
