I followed a pin to a tutorial by Martha Stewart (wouldn't you know). I couldn't find tissue paper in the size she recommended, everything I found was either square 20"x20" or 20"x16". What I did learn from this is it is best to start with rectangular sheets of tissue paper as square sheets resulted in pom-poms that were not as full looking.
So following the instructions I stacked 8 pieces of tissue paper together (either the 20"x16" or the 20"x20" cut into a more rectangular shape). My first attempt, I didn't quite read the directions correctly and folded each individual sheet before stacking them together..............yeah, that didn't quite work out so well, my pom-pom wasn't very round or full.
I also found out it's important to fold the tissue paper across the longer length (i.e. so there will be more folds, not long folds). Once again when I did it the wrong way my pom-pom failed to be the nice round and full shape I was hoping for.
After the sheets were folded (the correct way), I used floral wire to wrap around the center of the tissue paper, with enough excess wire for hanging.
I then trimmed the ends of the tissue paper to points. You can also make the ends rounded for a softer flower like pom-pom, but per the super hero theme I wanted the pom-poms to look sharper, like "kapow!" poufs if that's a thing :o)
And here you can see how it looks when the folds are stretched out:
Lastly, I separated each of the eight layers of tissue paper to form the pom-pom.
And then I had a pom-pom:
...........or "kapow!" poufs.
