I've tried to overlap words when making maps but I'm not sure on how to do it. when i tried to do it, the words got messed up and i had to try again. How do you do it?
First off, you need to get the Overlap Front and the Overlap Back marks.
The you place the Overlap Back Mark "Text" and Overlap Front Mark"Text".
You will need to aling the two text bodies by placing spaces in front of the whole text, behind or in between the two textx. Remember that the only way to get the perfect align is by testing.
The tutorial only gives a guideline, however, so feel free to experiment to make it how you like it. Go for it!

you can also triple lap by using the overlap back mark again.
Can you quadriple overlap?
You can but the word probably has to be pretty small or it won't fit. Won't overlapping four times just make the word very blurry?
its all in the tut. that legacy linked to: Double Overlapping, Triple Overlapping, and Quadruple Overlaprping. So yes, quadlapping is possible. The tutorial for all of these are in the same one.
Whats funny is most of the time the 4th in the quad laps is used the align the other 3 words.
