Small animals tend to live shorter lives than larger animals. There are a few theories as to why that is, but the one I believe is most popular is: small animals tend to live shorter lives anyway (because of threats from predators), so there are fewer opportunities to evolve to be long-lived.
The American National Standards Institute (ANSI) Class 150 is a system of dimensional standards for weld neck, threaded, slip-on, lap joint, socket weld and blind flanges. Dimensions for facing, bolts and studs are also included in ANSI Class 150. ANSI Class 150 establishes measures for pipe sizes.
One way is to use leftover binding strips from other projects. Piece them together until you have the length you need. A binding flange is a folded strip of fabric that rests between the binding and the quilt front. Flanges are great when you need a tiny pop of color before the binding. They can also be used to separate busy fabrics used in blocks from a busy binding.
