I was wondering if anyone has any knowledge of the NYMO beading thread. I have descovered that there are a number of different sizes and I'm not sure what the difference is. The sizes I have been told are D, B,O,OO etc. I want to make bracelets with seed beads, bugle beads and sqaure beads. I'm just not sure what size thread to use. Please can anyone tell me anything they know about this thread and their experiences with using it.
