On increasing the neckline of a medieval tunic

This is a very brief follow-up to a post in which I made a medieval tunic just to realized that something went wrong during our collaborative measuring and drafting and so the head of the recipient F barely fit through the neck hole. Now, for men's tunics, a socalled keyhole neckline wasn't unusual: the neckline itself is not low but it has a cut to fit the head through that then is tied closed once the tunic is on. This is exactly what I did:

1. find middle
2. cut ca. 3cm
3. re-hem sides of cut
4. pull thread through newly formed corner, creating long loops
5. weave long loops to form ties to close the keyhole

Formalities:

• Materials: thread
• Tools: scissors, needle
• Time: about 1 hr
