Look into Lighthouse, Schaubek, and KaBe albums. One of them, I believe, still sells linen-hinged pages, but I can't remember which. The first two have websites in English, and the third (KaBe) is sold by Lighthouse.
Ah, just found it! It's KaBe. Their pages are somewhat larger than the other sellers' pages, and you'd need to use one of their albums to hold them, presumably. Also for the life of me, I can't find any indication of the number of pages you get with KaBe. Kind of important, I'd think. Here's a link to the pages. They're probably pretty expensive.
https://www.lighthouse.us/kabe-blan...n-hinge.htmlSchaubek sells some excellent quality blank pages, including pages which have scored grooves to simulate linen-hinging. And they're very inexpensive to boot, about 35˘ a page or so. Worth considering. As much as I love linen-hinged pages for their elegance and ease of use, I'd use less expensive pages like the ones with the grooves which can also be turned easily but which won't make me angry when I misspell a word or draw a stamp box wrong and have to start over on a new page.
These sellers also commonly use long cut-outs on most of their pages in place of scoring of grooves or linen-hinging to make their pages turn more easily, but I find the long cut-outs unpleasant and a bit silly looking, so I try to avoid them.
