The barn where I set up my pottery studio was covered in clay tiles. Ideal for ventilation of hay or grain underneath and cooling in summer. But not for potters shivering under as the cold weather was setting in. I soon realized that the roof needed insulation.
A quote from a builder was astronomical. It needed high scaffolding and quite some time to be done, he claimed. I simply couldn't afford it. The threat of closing down was on again. Then Hadrien said he could do it no trouble... He turned up with a long ladder. I borrowed a gun stappler from a cousin of mine. He went to the local Do-It-Yourself shop, got some insulation material, put the bill on a business account he opened in my name, came back with it and went up the ladder.
It took him two days. I did have an insurance but if anything had happened to him I would no doubt have ended up in jail... This job was not really included in his contract for apprenticeship.
