I have the same problem
I think I will check into some of these tips
I did take a quilt class once and the teacher had an awesome tip and it work wonderfully. She had us sew to the front (I think - might not be remembering correctly) then when you flipped the quilt over she showed us how to "feel" where the binding was on the other side. That helped keep things even - and I did 2 quilts that way with her and I was sold on the technique - it really helped me alot.
the only problem that she also uses fusible batting. I like the fusible batting, but it just adds expense. I think this method would probably work with 505 spray - or maybe a quilt that was long armed.
since I am so tight wadded I maybe get 1 or 2 quilts long armed a year... and I can't get myself to spend the money on fusible batting. I use the elmers glue for basting and that leaves residue that I can feel so I can't feel my binding on the opposite side when I am sewing. Maybe some day I will win the lottery and money won't matter ha ha
