I did one QFKs with the binding wrapped from the back, but I didn't like it. It just didn't seem like it would take the wear a traditional binding. The last two I've done with a traditional binidng. I found some fabric that worked and just machine sewed it on like I normally do. QKFs says it is ok to do with the self binding from the back or to add your own traditional binding. They do say it has to be completely machine sewn though - no handstitching.
