paper flag banner D.I.Y.3:20 PM
Incredibly easy to make, just takes some time. Get 4 different colored pieces of 12x12 craft paper, you can fit 3 flags on one sheet. My triangles are 6 inches wide, by 7 inches long.
(I had some that had patterns on both sides which was nice because it gave me more patterns to work with).
Next, take your ribbon and lay it out straight, don't cut it until you have layed out all of your triangles. Then hot glue each triangle to the ribbon and cut.
