My wife and daughter recently attended a bridal show and were particularly impressed by one photographer's albums. This was the only one showing creased (seamless?) album spreads. I searched on durability but only found some older posts. The search suggested either durability problems or visual discolorations along the fold after a while. Does this still present a problem over time or have processes or materials improved? Is this something that looks good but perhaps should be avoided for the long haul?
