On my current quilt I am using Isacord (polyester). I was stitching away having a great time and very pleased with the results using Isacord on top and Superior Bottom Line in the bobbin. When I had a thread that wouldn't pull to the top, I turned the quilt over and almost cried: the tension was wacko. I had those little thread pokies on every sharp turn of my feathers, and the micro-stippling (silk and Bottom Line) looked like a starry sky on the back because there were so many pokies that were long. This happens when the upper tension is too loose so the bobbin pulls the upper thread visibly to the back. I tightened the tension and played with it a bit on my sample scrap, but it didn't help. Re-threading the machine and changing the needle was no help either. Next I spoke to my professional quilter daughter who suggested I put cotton in the bobbin. So I put the quilt away for 24 hours!

The tiny feathers were next. The front looked fine, but the back was too sloppy to suit me. I still want to use Isacord because I love the sheen, so I decided to use it both top and bottom. Beautiful! I'll have to do some ripping, but it will be worth it.

TIP: This is strictly my own opinion. I was told by my machine dealer that Bottom Line has a little elasticity and when it relaxes after being stretched in the stitching process it puts too much tension on the top thread and pulls it through. I haven't talked to the Superior Thread company, but if I use Bottom Line again I will do a more thorough test run before stitching my quilt. Isacord is not a Superior brand thread and my machine is clearly unhappy when I try to match it with Bottom Line.
Sew some happy seams this week. I wish you no tension mismatches, no bumps, loops or pokies.
