How does 20oz batting differ from 6oz or 9oz polyester?

The oz weight refers to the density of the polyester fill per square yard. 20oz is significantly thicker and warmer than 6oz or 9oz — it produces a thick, comforter-like loft. Use 6oz or 9oz for lighter, flatter quilts and 20oz for maximum warmth and puff.

Can I machine quilt through 20oz polyester batting on a longarm?

Yes, but needle penetration requires more force through the thicker fill. Use a sharp needle (size 18 or larger), reduce speed slightly, and ensure your machine is properly tensioned. Quilting lines spaced further apart work better with high-loft batting.

Will 20oz batting beard or migrate through the quilt top?

Hobbs polyester battings are bonded to resist bearding. With normal use and proper quilting density, bearding should be minimal. Avoid very open quilting designs with spacing greater than 6–8 inches.

Is 20oz batting suitable for hand quilting?

20oz is a very thick batting that is difficult to hand quilt through. This weight is best suited for machine quilting, tying, or comforter-style construction rather than traditional hand quilting.

What thread weight works best with high-loft batting?

A heavier thread like 40wt or 30wt polyester shows up nicely against the thick loft. Fine thread can sink into the batting and be less visible — use decorative thread if you want the quilting design to be prominent.
