▶ Our VerdictOmni is the everyday workhorse — twice the yardage, lower cost per yard, and great for top and bobbin. Bottom Line is the specialist: when you need an ultra-fine thread that virtually disappears into the quilt top, nothing beats it. Many longarm quilters use Omni on top and Bottom Line in the bobbin.

Who Should Choose Which?

Choose Omni if you…

  • Want the best value per yard
  • Do high-volume pantograph quilting
  • Want thread that shows your quilting design
  • Prefer a slight sheen in the finished quilt
  • Run a longarm business and buy in bulk

Choose Bottom Line if you…

  • Want thread to blend into the quilt top
  • Need a dedicated bobbin thread
  • Do applique or fine detail work
  • Want the finest, most invisible stitches
  • Quilt busy pieced tops where thread should hide

Frequently Asked Questions

Can I use Bottom Line as a top thread on a longarm?

Yes — Bottom Line works as a top thread but it is lighter and finer than Omni. It's most popular in the bobbin where its fine weight reduces bulk in the quilt sandwich.

Why does Omni have twice the yardage for less money?

Omni is 40 weight — heavier per yard — so the cone holds more thread by length. Bottom Line is 60 weight, much finer, so you get fewer yards on the same cone size.

Which is better for stippling and feathers?

Both work well. Omni shows the quilting design more because of its 40wt body. Bottom Line blends into the fabric so the quilting texture shows rather than the thread line.

Is it okay to mix Omni top with Bottom Line bobbin?

Yes — many longarm quilters do exactly this. The combination balances visibility on top with minimal thread bulk underneath.
