Have seen lots of photos with a balloon around the outside of a balloon topped off with a balloon bow on top.
Can you help with the bow unable to do.
I am not sure if I understand fully what you have in mind. But I guess you are talking about a double bubble balloon (one balloon inside of another), topped with a bow made of a twisting balloon.
I found a balloon twisting video
that shows how to make a Christmas Wrath with a bow.
At 1:40 minutes into the video he starts with the bow.
Some basic pointers about balloon twisting, including the "pinch twist" which you'll need for the bow are on my page about balloon animals
If that's not what you had in mind, Jackie, please submit a photo of the decoration you'd like to make.
All the best,
