You can get a quite decent ‘hand-drawn’ look by using a brush on a vector line.
See attached image and document. Have a look at how I have used the different line lengths to simulate the pen line being drawn differently.
Not perfect by any means, but quick.
P.S. The ‘Minor’ group of objects in my attached example shows one way to create dashed lines in a similar way but it’s very messy and I wouldn’t advise using the same method, but it might be useful to know about.
