Making binding is not my favourite part of quilting, so I make a few extra yards when I’m already cutting and ironing some anyway (tutorial here). Running another yard or two or five through the bias tape maker does not take that long when you’re already ironing, but the benefit is great.
I now have a Big Bag of Binding full of different coloured binding to choose from, most of them ready to use. Some are long enough to bind a large quilt; others are just scraps that I at some point will piece together for smaller or scrappy quilts. Lots of fabrics I don’t really like that much (great for binding though) also make it into my bag together with leftover 1 1/2 “ strips.
It’s kind of having an extra bank account; time is money, isn’t it?
