Well, I have a
and two shortbread fingers.
I have also decided that this is probably my best option for my archive:
https://www.amazon.co.uk/Really-Use...coding=UTF8&psc=1&refRID=Y1ER7ZX113GRN0CD2JFT
And with individual sections bound in report wallets - which gives me the flexibility to add and move items whenever necessary.
It's a shame I can't keep everything in one file anymore - it's lived in this one since 1992, and prior to that, three exercise books. But I just have too much stuff, and in the absence of bigger arch lever files i.e. with spines wider than 85 mm, I have to be realistic. I could get an 85mm arch lever, but it's only 5mm wider than what I already have, and I'd find myself with the same problem again sooner rather than later
Just need to figure out which size of box I want - big enough to be future-proof for a good while, but not so big as to be unportable and unwieldy...
I'll find myself eventually...
