I know, girls are so much value aren't they! It was just the look on her face when she told me, sort of like 'ooopsie, I think I've made a mistake!'
TBH it's actually quite funny.
The cupboard is the one immediately below the sink so there is no draw above and lifting the worktop is not really an option. Coat hanger sounds like an option. The wife also thought that some string hooked around the door side might work.
You see that's what I love about her. She's daft as a brush enough to make a hash of the job in the first place, but sharp as a razor to then come up with an ingenious idea to fix it!
