I join many in regarding Allan to be of the finest Bible binders (perhaps i'm biased).
If you have a Bible bound by Allan's you really don't need to read the rest of this post . . . seriously you don't.
One of the things i've often thought of is 'what if someone loves the Bible they have, but, without changing the actual pages (text block, personal notes etc) they'd love to change to a higher quality binding and add their own personal touch (extra ribbons) ?'
Now there's a guy called Paul Preston who will build a Bible to your specifications or rebind your old one with the binding of your choice.
Matthew Blair (The Foolish Galatian) writes about Paul:
"Sure there are binders out there that can offer custom work. But you will not likely find one with such a burning passion for Gods word..."
