Meyert, can you post a pic of the binding problem? I use a modified F &P method to join the ends that is fail proof---I leave about 10-12" tails at each end (actually the L hand one when it's laying on a table with the edge at the top needs to be about 15" or so--I save all the tails for string quilts). Then I fold back each tail and leave a 1/4" gap between the 2 folded edges(not with a bias binding! I use about a 3/8" gap with them). I press the folded ends and then open back and put the right sides together on the bias, matching the press lines and pinning like crazy! This is just like putting 2 stripes together on the bias to make a long strip---but you will have to scrunch the quilt up to get it pinned. Sew it together and pull it to check to make sure you did not get a twist in it. If no twist, trim and sew the rest of the binding to quilt.
I sometimes get "bad"miter at a corner--any tips there??
