Just hand sew it...that happen to me also when I handed sewed my son's. If you decide you don't want to keep that binding. Just use the seamripper and begin over .I machine sew bindings only now. So much easier. Also make sure you wash the material first. Other wise it does shink and pulls...I also sew the outside of my quilts before binding it. and when i sew on a border I sew it twice. After working hard on quilts I am learning the the extra work is worh it.
