visit Superior Threads web site- they have TONS of great free information- charts you can print off - that will answer your thread questions-
their Bottom Line thread is a great bobbin thread- fine and strong- you can get alot on a bobbin( so you don't have to stop to re-fill so often)
they explain the differences in threads, what they are best suited for and the needles to use with them- explaining the differences in needles and sizes. a very good informational resource. (and --no, i'm not affiliated in any way- i just learn alot from them)
usually i just use what ever thread i'm using -- top and bobbin--
and the (afraid of poly thread???) i don't get that at all....poly thread has been around for a long-long time and is a good thread for most uses....much less lint than cotton and comes in a huge selection of colors along with weights. i use some cotton threads buy many more poly's...they certainly won't hurt your machine.
the thread that will hurt your machine is one specified as Hand Quilting Thread---it has a wax coating which can cause big problems- if it says it's for Hand Sewing don't use it- if it is for machine work---try it out-
there are so many wonderful threads on the market- it's a shame to limit yourself -- the new varigated threads are fabulous! i love sewing with silk thread---it is so smooth--no lint---glides beautifully... don't limit yourself- educate yourself-
