I have a pretty old book that has a hard cardboard sleeve that’s really frayed at the corners, so that the bottom part of it is coming off a bit. What kind of glue would you use? I want to keep it from fraying again or damaging/having weird effects on the material over time.
Wouldn’t tape be better? Something like thin crystal Tesa? https://www.tesa.com/de-de/buero-und-zuhause/tesafilm-kristall-klar-ean-4042448036285.html
Unfortunately does not seem to be available wider than 19mm. But the industrial stuff is much wider, and very thin.
Thought about this, but another book of a similar age has tape like this on it and it unfortunately turned yellow and opaque and covered up what was underneath. It’s old tape so maybe modern tape doesn’t do that? But I’m not sure how to be certain.
