I'm a fold-and-hold fan too. But often will end up using the "just eat them all" strat.

I'm torn. In an emergency it may be your only option... however it is clearly not good biscuit care. I vote ingenious in an emergency, travesty in all other situations

I usually carefully fold the end so it's tight, then place it against the wall or another item in the pantry so it can't unfurl (assuming it's too short for clips)

I'd be lying if I said I'd never done this, although usually it's the side of the cupboard. I think if you twist it first, you get a good enough seal that it works well.

I combine this with the twist and tuck. The wall helps it stay in position.

Bag clips from ikea have become a way of life, can't imagine going back.

me:

1. twist end and fold down tail
2. slide open box down over biscuit sleeve
3. flip box so gravity holds twist & tail
4. forget
5. remove sleeve, it untwists, biscuits dump unceremoniously into box

don't be like me
