Mine are on the bottom shelf in a cupboard in the kitchen, because I do so much freezing. The whole half-cupboard was a dreadful mess of mismatched tops and bottoms until a month ago, when I hauled them all out and sorted them.
I was just about to recyle all the oddities, having found that most that I wanted to keep would fit into two neat piles, when unfortunately DBH came past, saw them in the recycling basket and said 'You can't throw those out! Some of those are my favourite raspberry and fruit-collecting containers!' Dammit, caught red-handed, he is such a hoarder.
They have gone down to the shed in the veg garden now, but of course he brought them back up to the house every time he picked fruit. As he is away, today I seized the opportunity to get rid of half of them. From now on, no 'useful' little container will be allowed anywhere near my nice neat tidy cupboard.
