It's getting to be this way everywhere. I bought some stuff from B&B, via their online iteration, when I was last in England. Other than that I rely on Kenton.
It's annoying though, having to send off to other countries all the time. It's at the point where you go into a so-called 'specialist' sewing shop, allegedly supplying the fashion schools, and they don't stock proper needles, chalk, any proper canvas etc. And then all the blank looks when you ask for these things. Makes me livid.
