Hi, this is my first post on Crochetme. I've been crocheting for nearly 2 years and just LOVE IT!

I've just downloaded this great tapestry crochet pattern from Carol Ventura. It asks for size 3 wool cotton thread from DMC, I've never bought crochet cotton thread before, its sooooo confusing!! I can't find size 3 cotton thread anywhere in Australia, the largest is #5. Could this be our 3ply cotton thread?

Is bedspread cotton = #10 cotton?

Any help you can give will be appreciated.
Thank you,
Linda
