For Landon's birthday party, Ava and I made streamers from construction paper cut into squares and sandwiched between two pieces of contact paper. Then I cut them into a spiral and we hung them up. They turned out pretty cute. We also made some smaller ones simply by cutting a sheet of construction paper into a circle/oval and then into a spiral. Here is another way to do it with shipping tape and tissue paper at Frugal Family Fun blog.
