Cut triangles from just about any fabric you like. Mine measure 10 inches tall by 8 inches wide. I love my rotary cutter and matt for this sort of cutting which would otherwise take hours!
Place two triangles right sides together and sew the two longest sides. I've used a 1/4 inch seam allowance but it doesn't really matter as long as the seam allowance is the same for all the triangles.
I found a 25mm wide ribbon or tape is about right. Be sure to leave about a metre at each end of the bunting for tying.
Place the ribbon flat on your sewing machine and place the first triangle right side up half covering the ribbon. Fold the ribbon over the triangle so that the raw edges are covered. Zig Zag stitch the ribbon in place.
