Making a Paper Triangle Banner (Bunting)

I'm preparing for Talia's birthday party and I wanted to try making a paper triangle banner (is there a technical word for that? I'm answering this myself- I looked it up. Bunting.) instead of using streamers this time. I pulled out the ol' scrapbooking paper and here's what I came up with:


If you've got 12x12 paper, you can use the same method I did (I found the idea at Creation Corner). If not, and if it doesn't matter whether the paper looks nice on both sides, you can use this idea from The Magic Onions blog.

I used 6 different pieces of paper & got enough triangles to make 4 (double sided) triangles per pattern. This makes a pretty long banner.
