Here is the pattern for a mid-length stand collar mantlet.
The stand collar section requires stiff fusible interfacing for stability.
It's an extremely simple pattern, making it ideal as a base pattern.
After printing, paste it according to the pasting line,Cut and use.
The pattern has a seam allowance, so it can be used as is.

This is not always perfect and I apologise for any parts that are difficult to follow.
(1) After ironing “Hard fusible interfacing” onto the “Collar Lining,” sew the “Collar Lining” to the “Bodice Lining” and press the seam allowances open with an iron.
* Make incisions in the split seam allowance (S/A) to secure the fabric.
(2) Sew the “Collar” to the “Bodice,” then press the seam allowances open with an iron.
(3) Pre-press the edges of the opening at [(3) position] to shape them (for both the outer and lining fabrics).
(4) With the outer and lining fabrics of the cape placed right sides together, sew around the perimeter from the starting point to the ending point at [(3) position].
* After sewing, trim the seam allowances at the corners.
(5) Turn the cape right side out through the opening, then press it with an iron to shape it.
(6) Topstitch around the perimeter of the cape to close it.
* At this time, also sew closed the opening.
* If topstitching is inconvenient, you can use iron-on adhesive tape to close the opening.
