I decorated some sugar cookies and had a few problems. First is why did the black outline run? I outlined and then let it dry overnight and most of the next day before I filled them with the orange. The second thing is I seemed to have gotten air bubbles in the icing creating small pockets. Any clue why??

Thanks in advance...Trance

Trying to attach pic...but it's not letting me. Maybe it's something Im doing. I will post it in my photos

Air bubbles happen, but as soon as I have put the run-in icing on, I go back with a toothpick and burst any bubbles, then push the icing into any spaces left.
