Best way to create a line inside a shape with fill
Hi there,
I am tryinf to create some shapes in Illustrator that act as "folds" or "creases".
What would be the best way to do this?
This is the shape I have created:

As you can see the line on the left going inward doesn't join anything. I drew the shape and then joined another part to it. I will be moving the upward line on the left upwards to it appears in the stroke of the other line but wanted to know the best way to do this.
Would it be best to create a complete shape then then add in a single line to create the effect or to do it similar to how I have done it?
Any advie would be great, thanks!
