The only problem I ever have is getting that last join in the binding, so that the binding is the right length to fit exactly on the quilt. I usually get it right, but it is an awkward seam to sew with the weight of the quilt at hand, and then sometimes I have stretched too much or not enough on the quilt edge when measuring to decide exactly where the binding joining seam should go. In that case, the fit is not perfect, and I have to rip the joining seam and try again.
It amazes me how many "not so good" bindings I see on quilts. I think that for some new quilters, they have not seen what the standard in binding looks like, so they don't know what they don't know. Also, by the time comes to put the binding on to finish a project, some people have lost patience or interest and try to hurry through it.
To me, the binding is what makes a quilt look professional. An average quilt made with average skill can be upgraded in appearance tremendously with a skillfully applied binding. On the other hand, a wonderful quilt loses some respect when it has a sloppy binding or one without nicely mitered corners.
