I'm another Aurifil girl - cream, beige (tan), grey and black. Over here there's very little difference in price between Aurifil (£8.00 for 1300 metres) and Gutermann (£6.60 for 800 metres).
In fact, now that I see it, Aurifil works out
cheaper!
I'm also about to switch to the variegated for quilting too.
