Very easily made bunting. This is double sided, cut with pinking shears, and the size of each pennant is nine inches long by five inches wide at the top. This one is ten metres long but could be any length depending upon available material and ribbon for the binding and ties.
To make bunting you will need a strip of fabric only nine inches wide - try to coordinate the colours, and each triangle is then cut on the zig zag leaving the remaining zig zag strip for other triangles. Two pieces are then sewn together back to back, and the edges trimmed with pinking shears (can be cut with these anyway).
