Indigo a blue to dye for

A fantastic exhibition on indigo is on at the Whitworth Gallery in Manchester, and will then tour the UK. Did you know woad and indigo are one in the same thing? That indigo is the only true blue dye? That it has to ferment to be released from the plant, and that ancient people used to use post menopausal women to work the dye vats, as they feared fertile women soured the process?
And then there's jeans,jeans,jeans, Thank God for denim and Mr Levi Strauss. They changed post war Britain that's for sure.

And blow me the Indigo Girls on are tour here too. I didn't know and so I haven't got a ticket. They have a new album out called "Despite our Differences"
It includes as song called Little Perennials so as a gardener I've got to love it.
