Take a piece of ribbon in you desired length.
Cut a second piece of ribbon 1 inch longer than the first
Sew or glue together the end
The bow should now resemble a loop
Finding the centre, fold each edge of the ribbon behind itself towards the centre- this will give you the pretty bow shape.
Using your spare hand wrap cotton around the centre of the bow
Repeat this again for the second bow
Place the smaller bow on top and line the centres
Using a thinner ribbon wrap this around both bows covering the cotton
Glue or sew the end
Using a hot needle CAREFULLY make a hole either side
Apply a jump ring and attach to a chain
Decorate as desired!
