Adding to the previous tip on multi-color lines there is a much more convenient way when all you need is a 2-color dashed line!
In Corel DESIGNER X5 you can apply halos not only to callouts, but also to any curve or geometric (line) object.
Since the halo can be generated with a color, you can use the halo of a curve as background, with a dashed line as foreground color element of your 2-color dashed line.
You can edit the curve with any Shape tool as it's still one single curve object.
Overthinking is something we all do at some point, but if you are getting lost in your thoughts often, know that you are not alone. Therapy can be a great way to understand why you are overthinking so frequently, identify triggers that may cause your overthinking, and figure out ways to stop overthinking everything. On top of that, a therapist may be able to help you improve your overall wellbeing from anxiety and stress to sleep patterns, a therapist can help in different types of overthing.
