ASSEMBLY INSTRUCTIONS
(Follows your shortened style—concise but clear)
1️⃣ Sew Side Seams
Place front (1) and back (2) right sides together and serge both side seams with a ¼” seam allowance.
2️⃣ Hem Asymmetrical Skirt
Hem the angled bottom using a ½” hem and stretch stitch. Tuck the point under for a clean tip.
Optional: For slinky/ITY fabrics, use a rolled hem or narrow serger stitch and gently pull fabric to create a ruffled edge.
3️⃣ Attach Piece (3)
With right sides together, sew the large side of piece (3) to the front (1). Ensure text is facing upright for correct orientation.
4️⃣ Optional Bust Ruching
Sew ⅛” elastic along the cleavage line while gently pulling to create gathers.
5️⃣ Apply ¼” Elastic
Using an elastic foot, sew ¼” elastic around all openings except the S-hook ends.
6️⃣ Finish Edges
Fold elastic to the inside and topstitch using a cover stitch, zigzag, or stretch stitch.
7️⃣ Attach S-Hook
Slide one back strap end (piece 3) through the ¾” S-hook, fold over ½”, and sew securely (two passes recommended).
8️⃣ Loop Side (Opposite End)
Fold the opposite back strap end to form a small loop and stitch. Keep the loop snug but able to slide on and off the S-hook smoothly.
