What I learned! (A brief one this time)
Cut the end of the bag smaller than you think you need (seriously)
There are always more air bubbles to pop.
If you think the icing is too thin, dump it into a bowl, add a bit of icing sugar to thicken, and re-bag.
This last is a total pain in the butt, BUT completely worth it! You will get to know the icing better and wont end up throwing expletives at sugar cookies when your details run.

As always, mad props to the original designer Megan Warne for her fabulous cookie designs. Thank you for helping me learn.
