....... lets get sewing (or sticking for those of us that like to cheat)
You will need:
Vintage Fabric and thread (or why not think of cheaply using magazine adverts with bright colours or pretty paper for quick and easy idea)
13mm-wide bias binding tape or really pretty ribbon
pinking shears or scissors
1) Draw a triangle the size of the bunting you would like, on some cardboard and cut it out to use as a template.
2) Pin the template to your fabric and cut around it using pinking shears to avoid fraying. Repeat until you have enough flags.
3) Evenly space the flags along the bias binding tape, or in the middle of the ribbon, folding the shortest edge over, and pin in place.
4) Sew on the flags with a straight stitch, or hole punch along if using paper and weave in and out leaving at least 40cm of tape free from flags at each end for hanging.
