I discovered an inexpensive bias tape maker online a few years ago. I got a set and researched how to use it. I love that I can easily make bias tapes for my projects. Buying ready made from the store can be expensive and there's not that many options. Learning how to make my own binding changed the way I do my projects.
I made a tutorial video on how to use the bias tape maker -
Hope this helps you make your project easier to make!
