How to overlay layers

[Krikor]

Pixlab and Rich2005,

I really appreciate your help in this case.

I paused part of a project just because I couldn't combine the layers as I expressed in this topic.
Fortunately I'm still on time and now I can proceed without further ado.

rich2005, I confess that I couldn't understand just through reading. Or at least not after a few tries; maybe if I persisted... maybe. But luckily the short film (45 seconds) was crystal clear.

Thank you very much.
