I just got back from Paris last Sunday. :inlove: I LOVE PARIS!!! However, there aren't a lot of yarn stores. I did manage to get to a couple -- La Droguerie is not far from the Louvre and there is an Annie Blatt store not far from there either. I wandered around and around La Bon Marche where there is supposed to be a Phildar store but I never did find it.
Just so you know, nothing is cheap in Europe at all. The Euro is something like $1.36 in dollars and in London it's $2 American for every Pound Sterling. So, there aren't many bargains.
And really, all the yarn I saw was lovely, but nothing really that you couldn't get in the States or online.
Now, the champagne, the pate and the coffee -- that was another story!
Oh dear, I forgot to mention le frommage!
