Hi,
I have just used all Aurifil on some William Morris appliques from Michele Hill's book, it has a really nice sheen to it and the work came up very well. I have also used Mettler but was more than happy with Aurifil. I bought mine from Tristan in Canada too, no one close to me in Sydney sells it and I had tried some that I got at the Craft show here earlier in the year. It is a really great thread and the colours and range are fantastic.
