Just when I think I'm getting the hang of this stuff, I have a disastrous batch. I used the Toba Garrett's icing to flood. I got my normal white (sugar-crystallizing) bumps. 
I did the detailing with royal icing. After detailing, I watched carefully with my pin in hand. 
Nothing, whew! I left the house and when I got back, I had not just little air-bubbles but major pot-holes! I notice some websites suggest to use the paddle when mixing to prevent air bubbles. What if I don't have paddles? Any tips or suggestions?
Also, how do you mix colors in without adding air-bubbles.

I found (on a chemisrty site) that lukewarm water has less oxygen than cold water, that might help 
While not a suggestion, I always mix my royal icing with a paddle for that reason. I've always had problems with air bubbles until I switched to a paddle. Same with warming up buttercream. Perhaps mixing whatever icing you're making by hand as suggested above?
