I love replacing my zipper pulls with contrasting ones or just prettier pulls, and while the first few attempts at this might be frustrating (and sometimes being two people can help), once you get the hang of doing this, it's actually really easy! And being able to remove the zipper pull makes working with zippers in so many instances so much easier =)
A few examples of where I've used contrasting zipper pulls, isn't it cute?
I hope you will find this tutorial easy to follow and that it will boost your zipper confidence!
