Someone asked for a tutorial about dotted lines. You should be able to do some using this tutorial and this other one I made about brushes, but sometimes a simple example is nice to get a good approach to a board subject.
Quelqu'un m'a demande un tuto sur les points et les traits. Vous devriez pouvoir vous debrouiller avec ce tuto-ci et puis celui-la , mais parfois expliquer un point de detail est une bonne facon d'aborder un sujet plus large, alors voici. Ce tuto est en Anglais, mais vous trouverez la traduction ICI.

First of all. As in geometry, a Photoshop line is composed of a multitude of points. If the space between points is short or non-existent, then the line will be continuous. The first thing to do to understand this is to open the brushes window and create a brush with a spacing superior to 100% (look for: brush tip shape, spacing). See? Dots.
Then you will want some more fancy dots, maybe create a line that looks like stitches or suggest the flight of a bumblebee.
For this, you will need to draw a picture of a stitch, like this:
Or a simple rectangle, like this:
Make a rectangular selection of your point/stich/rectangle, and then do Edit>define brush preset. It works better if your point is an horizontal shape.
Then you need to open the Brushes window. Go to the "brush tip shape" tab. Select your new brush preset.
Define the spacing. Save the brush. Try the brush.
It doesn't work. It looks like this.
And you want it like that.
Go to the brushes window, click the shape dynamics tab, and choose Angle Jitter , 0%, with Control set to : Direction .
Et voila! You are now a happy bumble bee.
