take an old top and cut out a Square (cut the square on how big or how small you want your bow)
Its best to cut it at the bottom of your top where the bottom lining is. ( you will fine out why next!)
Now you have your square cut off the bottom lining and keep it for later on!
Now you should have your square and you bottom lining:)
with your square fold all your corners into the center so its like a diamond shape.
and sew lightly them corners down.
now turn you square over so the part where you've sown is face down. then scrunch from the middle with your thumb and index finger until you got it like this.
Then with your long piece wrap that round the middle and sow it.
(make sure that you saw it at the back, so you don't see the stiches!)
Then put a bobby pin at the back through what you have sown then your done! (if you want to keep your bobby pin in then you can sow over it so it stays secure!)
So try it out! :)
