Ok still no worries as long as you have enough length to do around the whole quilt then this measurement should work. I always cut my QUILT BINDING (is this the right B word??? :wink:) at 2 1/2 inches and I do what is called a double fold or french binding. That is where once you piece the lengths together you fold the binding in half and sew that to the quilt. YouTube has some great videos on how to make a double fold binding and how to attach a binding to a quilt. I am dyslexic and always have a problem joining the double fold binding together to finish off the quilt. The videos helped alot.
Don't stress, have fun! :D
