I don't have many buttons so I keep them in a jam jar. I do have old baccy tins full of allen keys though. They used to belong to my OH's ex wife's dad. No idea why he ended up with them, he is rubbish at everything to do with DIY.
But this has given me inspiration of buying a Danish BISCUIT tin for my OH for Christmas to go round and gather all the screwdrivers together and keep them in, as he is always bloody moaning about finding the right screwdriver. That's boxing day sorted. I never use them, I go get one of my drills.
I also have bad veins. I tried to explain this to a young French bloodtaker earlier this year and he smirked. Then he frowned. Then he muttered. Then he left the room. Then he came back full of vim and vigour. And I tried to explain about them having to take it from various other places before and he growled. After about 20 mins and trying several places he said i was right and yes, this is difficult. Finally he called a senior person in (female) who tried and got it on the first try. He wasn't happy.
