I had the same comment on a quilt. One I entered, the binding was done by someone else, another entered was my binding. The other binding quilt took second and mine did not even place. Did you sew the corners on your binding? The slit 90 has to be tacked down for show quilts. Were you sure to measure randomly around and that it was all equal? I have entered quilts very often. Mine have even made the top 50 on Hoffman Challenge. I enter quilt contests to see how well I am doing so I take the judge comments to heart. They can be cruel, but use them constructively. My bindings have improved enough now that I generally get a 9 or 10 on them. There are a couple of books out that help with suggestions on show quilts if you decide to keep going on. Also, small towns do not always get qualified judges for all categories of judging. Keep putting them in the shows though.
