Thanks guys :-) the problem isn't so much that the glue is stuck down too well, its more that I can't access the papers at all!
Anyhow, I'm not nearly as concerned as I was before I washed it! Now that it's dried out, it feels a lot less crispy than before it was washed, and I think that most of the glue is gone now! Its definitely less obvious that the paper is still in there, so I think you're right, the judges will have no way to know!
