Here I am using two different coloured ribbons. Take narrow pieces of the ribbon. Make sure that they are of equal length.
Take one of them and wrap it around your stick. You can use any narrow round shaped object for this purpose. Keep it like that for some time.
Do it with all the other ribbons.
Now take them together and tie a thread on the middle of the ribbons. Tie it tightly. See the bow is ready.
Now you can glue it to your hair bow.
So don't waste any more money at any boutique to buy bows, as now you know how to make it.
