How can I get the seams of wallpaper that is 18 years old to lay down?

The guy originally overlapped the seams cause he said it would shrink. Didn’t do that and I have just tried to ignore it but in the last year it is sort of curling up. I love the paper and really don’t want to replace it. Any suggestions. Thanks. Betty
