That's right! Two rocks of Quartzite and a bag of Potassium Aluminium Sulphate. Now I can grow my own crystals in the airing cupboard. (Note to self - remember to tell Charlie that I am growing Aluminium Sulphate crystals in the airing cupboard.) Expect updates.
The two charity shops on Mile Cross are a goldmine. I nearly came home with a genuine set of steel petanque balls that only had a light dusting of rust for £1.50! They could have lived so happily beside the (unused) table tennis bats (£1) and the authentic Yangzhou writing-brush kit (£2).
But it's the books that are the real bargain. Six for a pound on paperbacks. The Oxfam bookshop in the city centre charge a fortune for books they get for free (they will barely even take a donation from you unless it's a signed first edition hardback) and in the Golden Triangle you are looking at two to three quid a book.
And paucity of choice makes a decision easier. In the Book Hive on London Street, I can happily lose an hour and not buy anything because I want to buy everything. I've banned myself from going in there except to buy gifts. In a Mile Cross charity shop the six readable paperbacks out of two-hundred leap out at you.
