Superior threads are great and their web site is full of information on using the right needle with the correct thread. They also sell fabric!

Yarn or Fabric

I'm a Glide user for my quilting. I use either Connecting Threads or Omni to piece with.
I am pretty sure that FilTech ships internationally. I love, love, love Glide. I won't machine quilt with anything else!

I use Connecting Threads Essentials for sewing, and for FMQ I use Metro machine embroidery thread. For either of these companies, you can't beat their prices and customer service, but I don't know if they ship international.
