I always use binding made on the bias because it provides a stronger finish than binding cut on the crosswise or lengthwise grain. In addition, it easily follows curved edges while giving a professional looking finish and it isn’t any more difficult to make once you have found a technique that works for you.
I purchase fabric specifically for binding in one yard pieces. After I have several prints, I spend the day making binding for use on future projects. By making my binding ahead of time, it allows me to keep my momentum instead of having to stop working on my project to make binding. I probably have at least 20 different prints of binding at any given time in my resources.
Taking the upper point of your folded bias edge and bring it down to match with the lower point.
Turn your fabric, with the bias fold to your left.
