I like various threads. Really don't have a favorite, per se. I use whatever brand has the color I want for any given quilt. I very much do like 'Thread Heaven'. It is a thread conditioner. After I snip off the length of thread from the spool, I run that through the thread heaven. This product works amazingly well to reduce tangling. However, I'm not sure it's made any longer. But if you can find some, it's fabulous. You can also use beeswax for that purpose if you can't find the Thread Heaven.
