Joost De Cock b34a2ee2ed feat: Flat import of markdown repo
This is a flat (without history) import of (some of) the content
from our markdown module.

We've imported this without history because the repo contains our
blog posts and showcases posts content prior to porting them to strapi.

Since this contains many images, it would balloon the size of this repo
to import the full history.

Instead, please refer to the history of the (archived) markdown repo
at: https://github.com/freesewing/markdown

Notches

There are two types of notches. The default notch is a dot in a circle.

An alternative style shows a cross in a circle. This style is used to indicate the back of a garment. For example, on a sleevecap you may see a dot and a cross notch. This way you know which side of the sleevecap is the back (the one with the cross notch).

Why we chose these notches

In electromagnetism, a ⊙ symbol is used to indicate a flow of current coming towards you (to the front), whereas ⊗ is used for a current moving away from you (to the back).

You can also think of an arrow. When an arrow flies towards you, you see its tip (⊙). When an arrow flies away from you, you see its fletches (⊗).
