I do the beading is done with a single strand of button craft thread, I did try using beading thread but it's too stiff and the sharp edges of the beads would cut through regular sewing thread. The needles I use for beading are Japanese sewing needles sold by Susan Khalje on her website http://www.susankhalje.com/store.html (scroll down the page)...I have to admit it's a challenge to thread them with button craft thread and a needle threader doesn't seem to work, but they are really perfect for beading. I've noticed that it's a tad easier to thread if I follow Natalie's advice to knot the end of the thread cut from the spool (I suspect this is due to the twist on the thread) and I also cut the threading end at an angle to get it through the eye. The eyes are so small I haven't tried to expand the eye. For construction I use a large milliner needle, which is easy to thread for me. I also do the construction with a single strand of button craft thread.
