On Saturday I took the last photos of the St. Catharines Gardens on the 2016 tour. What a delight to find the owner is a Coppersmith and his workshop is in the garage. He was working on restoring copper eavestrough for a Toronto house, along with lamps that would originally have had gas for lighting.
He said that one of his challenges is making new copper match the old so that the repaired eavestroughs are attractive.
When I looked at the workshop table I remarked: "Look at that colour on the table." He laughed as he told me the colour came from Miracle Gro and that's what he uses to 'weather' the eavestroughs so they look old.
