That is a nice tutorial. I'm always fascinated by the number of these things that use fabric where the right and wrong side look exactly the same - making it extremely difficult to figure out what's going on. Case in point are the videos by Sharon Schamber. They are excellent and I always refer to them if I haven't done any binding for awhile - but the binding she's using looks the same on both sides.
If you are curious, they are YouTube "Binding the Angel". There are three parts. Part 2 is the one that deals with bringing the two ends of the binding together - something I initially found to be almost impossible.
