I like this idea - think I will have to print one out while I get used to getting rid. A card with a number of salient questions on it to help with decluttering:
---
How long has it been since I used this?
Do I like it?
Does it work properly? Is it broken?
Do I have more of this kind of thing? How many do I need?
If I keep this, what will I get rid of to make room for it?
Can I locate this information somewhere else (probably on the internet) if I need it?
