To make these sweet little banners, you need:
3-4 sheets 12"x12" craft paper
3 yards Bias Tape (I bought mine at Joann's)
1.) Cut as many triangles as you can out of each sheet of craft paper. I was able to squeeze about 5 out of mine with the help of my math-inclined hubbie.
2.) Slide the wide end of the triangle into the open fold in the bias tape directly in front of your sewing machine needle. Note: Start sewing on the bias tape for an inch or so before hand to get the needle placement setup and be sure to leave a few inches of bias tape on the end for hanging.
3.) Use your hand to keep the paper in the bias tape and sew right over the paper!
4.) Keep inserting triangles into the bias tape as you go until your banner is the desired length.
5.) Hang your banner(s) up and enjoy! See, I told you that was easy!!
