I can't use clear thread in my bobbin and I don't adjust the tension of the top. I would never laugh. It sounds like a question I would ask.

Don't have an answer regarding number for tension setting, but a caution...please don't mess with bobbin tension unless you know what you're doing...most tension issues can be taken care of on newer machines by simply working the top tension. Bobbin tension is more difficult to adjust and just as difficult to return to normal. As someone suggested, make a sample sandwich and try the thread on various settings....if you don't have an instruction manual for your machine you may be able to get one on-line

I never can remember if the lower numbers loosen the tension or if I need to go to higher numbers to loosen! I know stupid right.

I use invisible thread on top when sewing patches on my daughters girl scout smock or on a friends sons boy scout shirt. I always use regular thread in the bobbin though, and I never move my tension!

Oh come on, can't I laugh??? If you let me I won't feel as stupid as I usually am :mrgreen:

Ok, now let's all give out a collective laugh together.

Seriously, I want to thank all of those who replied because you answered my questions. I have a Janome and I don't believe I can use a metal bobbin in it. I never have had good luck sewing with the invisible thread. It constantly breaks on me but I use it in both the top and bottom which may be my problem.

Thanks again to all of you. This HAS to be the best group on the web, hands down.

Definitely no snickering here. I just adjust the top tension and test it out on scraps.
