Who knows a nice and easy way of making these tiny spacers? The ones on the pic are about 4mm thick and 7mm in diameter. They seem to be so popular all of a sudden, but they are such a pain to make! I find it tricky to balance a tiny amount of glass on my mandrel, keeping the wound glass in the way that it doesn't collapse on itself. Of course, as always, the place in the flame is important, i.e., temperature control, but also I now use industrially produced stringer instead of a whole thick rod, this seems to have helped. But then there is also the cleaning of the holes, which is fun: they are so small, and holding them simultaneously with drilling is a nightmare. BUT they do look cute in a finished jewellery piece, so... back to work!
