I've been asked by several people to send them a list of the tension settings that have worked for me while quilting with various threads on the Bernina 830 machine. So here goes....
All of the quilts worked on had Warm & Natural batting in them. Tensions could change if you are using a different batting, but these #s are a good place to start.
I have had great success using the Mettler Silk Finish 100% Cotton 50 weight thread in the bobbin with the various threads that I use. I have used poly and other threads in the bobbin, but not been as happy. I am currently testing Invisifil from the WonderFil thread company as a bobbin thread and have used it in a couple of quilts; it is working well and blends in nicely.
The first thread listed will be the one threaded through the top of the machine, the bobbin thread is in parentheses. The number will be the tension and the Auto or Manual refers to the needle threading method.
First, two water soluble threads used in trapunto by machine:
Vanish Extra from Superior Threads (Mettler Silk Finish 100 Cotton 50 wt) 2.0 Auto
Wash-A-Way from YLI (Mettler Silk Finish) 1.5 Auto
Next, a few monofilaments:
Wonder from YLI (Mettler Silk Finish) 2.0 Auto sometimes, but not consistently
MonoPoly from Superior (Mettler Silk Finish) 1.25 Manual (worked best with the thread net covering the spool)
Sew Art (Mettler Silk Finish) 2.0 Auto
Sulky (Mettler Silk Finish) 1.0 Manual
Jenny Haskins (Superior King Tut) 2.0 Auto
Invisifil (Mettler Silk Finish) 2.0 Manual
Invisifil is not technically a monofilament, but it comes in 30 colors and blends in beautifully without the shine of a monofilament thread.
And, finally, some of the decorative threads:
Glitter by Superior (Mettler Silk Finish) 1.25 Manual
Mettler metallic (Mettler Silk Finish) 2.0 Manual
Sulky rayon (Mettler Silk Finish) 3.0 Auto
