leatheroo Report post Posted April 3, 2014 So i have been buying poly thread from the thread exchange because i can't work out the aussie thread sizing system. I have spent many hours researching this, but i can't seem to find a plain answer anywhere. I know i what to buy US size 69 and 138 thread and the thread exchange has a nice chart for thread size to needle size. I found Anne Bonnys Locker selling 40 ticket thread that says is equivalent to #69 so that gives me some idea. Can anyone tell me the equivalent aussie sizing or point me to a conversion chart that makes sense? cheers and thanks caroline Quote Share this post Link to post Share on other sites
