Another project I did for my sister's baby shower was tissue paper pom-poms. I made them in pink, chocolate brown, and white, although the white ones fell down so we just left them down. These were super easy to make and looked really cute hanging around. I've seen them made two different ways. You can use the styrofoam and hot glue method. I used the Martha Stewart method, basically just because I had the stuff for that method.
It's tough to see, but there's fishing line there. After you tie the fishing line, I cut the ends of the paper to make it look more decorative. You can round the ends, so do a point. I cut the ends into a point because it's easier.
Next, flip the pom-pom over and follow the same steps with the other half.
Once you and finished, you should have a full pom-pom. You may have to adjust the layers a little once you hang it.
And here's a photo of one hanging at the baby shower. They made a nice backdrop. I might even make some little ones to hang in my classroom.
