You will need:
*2 or 3 different materials that coordinate with each other. examples: old curtains, sheets, clothing, etc.
*Scissors Cut out a hole bunch of triangles all the same size using the fabrics you've chosen.
Pic out two triangle you want together.
Cut off two inches off the top of the triangle you want over the other. Lay it over the triangle you want on bottom, the two top edges together. sew all the way around the top triangle.
Once you get the amount of triangles you want sewn together(we used 7) lay them out in the order you want them to hang.
Use the strip you cut off to sew all your triangles to. sew the top side of each triangle in a row to the strip of fabric. When your banner is done you can hang it where ever you'd like.
