2. Cut Your Fabric
Fold your fabric and place both the front and back pieces on the fold. Cut one of each.
3. Sew the Shoulder Seams
Place the front and back pieces right sides together and sew the shoulder seams. Press them open for a neat finish.
4. Sew the Side Seams
With right sides together, sew the side seams. Press them open.
5. Finish the Armholes
Finish the armholes with bias tape for strength and durability — especially helpful for active little ones.
6. Hem the Top
Fold the hem up twice and stitch to finish. Press well.
7. Sew the Back Closure
I wanted to add a stylized back closure to this top, featuring a keyhole opening and two tie‑strings that fasten at the back. Because of the higher neckline, the top cannot be slipped over the head without this keyhole, so the opening is both functional and decorative, giving the garment a sweet, vintage touch.
Keyhole Length by Size
These lengths ensure the top can be worn comfortably without forcing it over the head.
| Size | Keyhole Length |
|---|---|
| 1Y | 2.75" |
| 2Y | 3" |
| 3Y | 3.25" |
| 4Y | 3.5" |
| 5Y | 3.75" |
| 6Y | 4" |
| 7Y | 4.25" |
| 8Y | 4.5" |
| 9Y | 4.75" |
| 10Y | 5" |
| 11Y | 5.25" |
| 12Y | 5.5" |
These lengths are proportional to the neckline depth and shoulder width of each size.
Keyhole Facing Piece (Cut from Main Fabric)
The facing mirrors the keyhole shape and must be large enough to turn cleanly.
Facing Shape
A soft teardrop or oval shape.
Facing Measurements by Size
| Size | Facing Height | Facing Width |
|---|---|---|
| 1Y | 4.5" | 3" |
| 2Y | 4.75" | 3" |
| 3Y | 5" | 3.25" |
| 4Y | 5.25" | 3.25" |
| 5Y | 5.5" | 3.5" |
| 6Y | 5.75" | 3.5" |
| 7Y | 6" | 3.75" |
| 8Y | 6.25" | 3.75" |
| 9Y | 6.5" | 4" |
| 10Y | 6.75" | 4" |
| 11Y | 7" | 4.25" |
| 12Y | 7.25" | 4.25" |
Tie‑String Measurements
Two tiestrings are attached at the top of the keyhole.
Tie‑String Width (Cut Width)
1.5" (finished width ≈ ⅜" after folding)
Tie‑String Length by Size
| Size | Tie Length (each) |
|---|---|
| 1Y | 8" |
| 2Y | 8" |
| 3Y | 9" |
| 4Y | 9" |
| 5Y | 10" |
| 6Y | 10" |
| 7Y | 11" |
| 8Y | 11" |
| 9Y | 12" |
| 10Y | 12" |
| 11Y | 13" |
| 12Y | 13" |
Step 1 — Mark the Keyhole
On the back piece, mark the keyhole length using the chart above.
Draw a soft teardrop shape.
Step 2 — Prepare the Facing
Cut the facing using the size chart.
Interface lightly for stability.
Finish the outer edge (serge OR fold ¼" under).
Step 3 — Stitch the Keyhole
Place facing and back piece right sides together.
Stitch around the neckline and keyhole shape.
Pivot carefully at the keyhole tip.
Step 4 — Attach Tie‑Strings
Fold each tie‑string strip lengthwise, stitch, turn, and press.
Insert each tie‑string between the facing and main fabric at the keyhole top.
Stitch securely.
Step 5 — Clip and Turn
Clip curves and notch the tip.
Turn the facing to the inside through the keyhole.
Press well.
Step 6 — Understitch (Optional but recommended)
Understitch the facing around the neckline (stop before the keyhole).
8. Finish the Neckline
Use bias tape to finish the neckline. This gives a clean, durable edge and keeps the top comfortable for everyday wear.
