I have my cone hanging upside down from the chandalier. The cone is held by a binder clip that has a rubber band attached to one side of the binder clip "handle". The rubber band is attached to a large paper clip which is on the chandalier.
When I want to switch cones I just unclip the old one and clip a new one on.
I have three DSM and one of them has a little thread guide on top but the two others don't have athread guide so I tape a metal key ring or a paper clip near the spoolpin to use as a thread guide
There is another poster here who has theirs hanging from a curtain rod
