cut a piece of fabric 9″ x 6″ for the main body of the bow and a piece 5″ x 2 1/2″
Iron the bow centre in a bias tape style (Watch video tutorial to see how i do it)
Sew down both sides to close it and to also top stitch the other side to match
Take your large piece right sides together and fold it in half length ways, sew all 3 sides leaving a 3″ gap on the one side
Flip the entire piece right side out and close up the hole with a quick top stitch
Fold the bow in an according style and place the bow centre around the middle of the bow slip on a keychain at this point and then secure it all together with a needle and thread
the video tutorial has clear instruction how to do this (sorry it was late and i forgot to take some more photos haha)
