Welcome to the forum. First of all we are not allowed to post pics that do not belong to us on here. You need to post the link to where you found the picture. The owner of the picture has to be given credit by linking.
One of the ladies on here posted the link to the bow you are asking about. All you have to do is add a bottle cap. If you click on Search at the top in the blue bar and type in bottle caps you should get a bunch of threads that talk about making bottle caps.
