You'll need some paper. I like color with prints. You may use solid one or texture one.
I used a 12" by 12" and cut it to three different size strips (2", 4" and 6"). You might want it bigger or smaller, test out different size with different width papers.
Fold the paper back and forth, repeat until the end of paper.
Then bend the folded paper in half. You may keep the ends straight or cut it so it's rounded.
Connect the open ends at the back side with tape. If you want use both side, then just glue the open end together. (You might want to use solid color or both side printed)
You can see here on the red on, half with the edge uncut and the other cut rounded. I made a mixture of some cut rounded, some not, and some half rounded.
You may place it on the wall as wall decorations.
You may string them together and have it hang as banner.
You may glue it to sticks and stick it on ground next to the chairs as it leads up to the aisle.
This is fun, easy to do, cheap to make, and makes great decorations. If you have kids, they'll love it too.
