- Use Sewer's Aid lubricant on the spool (a few drops every once in awhile)
- Straight lines/walking foot will have less breakage than using curved lines/free motion
- Play with the top tension....usually need to loosen the tension
- Go slow
- Try the difficult thread in the bobbin and quilt from the back.
- Have low expectations. Know that the thread will break periodically and celebrate when it doesn't break for a couple minutes!
I've noticed that Sliver or Glimmer (which isn't metallic, but mylar strips) stretches a bit, so doesn't break as easily as metallic thread. No need to lubricate mylar threads.
My favorite brands: Sulky Metallic (the variegated tri color #143 is pretty cool); Superior Metallic and FS Madeira Metallic (which is metallic wrapped about a black core of regular thread which helps with the breakage and looks like tiny beading)
So share your frustrations and successes here!
