covering a notebook

[flights]

I'm pretty sure someone posted a really good way of getting neat edges when making covers for notebooks but can I find it?  I think it arrived as an email but maybe it was a blog I read.
It showed a clever way of not making the opening to slot in the book until the end of the process, thus saving the edges from getting stretched.
Does anyone recall something like this?
Many thanks if you do, otherwise I am just going to have to work it out for myself, which of course is no bad thing - just love trying out recommendations

Lindsay posted about a year ago about making wet felted notebook covers. Not sure if this is what you were looking for or not.

Thanks for posting the link, Ruth. I made them using a resist that is sized to cover both sides of the book including shrinkage. The wool is laid on one side and overlapped onto the second side only at the two ends where the book will slot in. There’s not a lot of cutting involved so it’s probably not the method you’re thinking of but feel free to ask questions if you want any more information.
