I love tissue paper poms. They are fun just to have up in the house! Trying to be economical for Hudson's birthday party I picked up a package of multi colored tissue paper. You can make those big full round poms easily with about 15 sheets of tissue, but my package only had 6 of each color. I could have cut the sheets down and made smaller fuller poms but instead I did half circles to be hung tight to the ceiling in pairs.
What you need-
4-6 sheets of tissue paper (15-20 for a full, round pom)
With all your tissue sheets in a neat pile, fold accordion style like a huge fan.
