Batting — the soft middle layer of the quilt sandwich — gets less attention than fabric, but it quietly decides how a finished quilt feels: how it drapes, how warm it is, whether it puckers in the wash, and how far apart you're allowed to quilt. Walk the batting aisle knowing these basics and the wall of packages stops being mysterious.
What Batting Actually Does
Batting is the insulation between quilt top and backing. Three numbers on the package do most of the deciding: fiber content (how it breathes and behaves), loft (thickness — thin battings drape crisply, thick ones look puffy), and quilting distance (the maximum spacing between stitching lines the manufacturer guarantees won't shift or beard).
The Main Types, Compared
| Batting | Loft & feel | Shrinkage | Best for | Watch out for |
|---|---|---|---|---|
| 100% cotton | Low (flat, soft drape) | 3–5% (first wash) | Traditional quilts, summer-weight, that "antique puckered" look | Needs closer quilting (often every 3–4″); gets heavier when large |
| Polyester | Medium to high (puffy) | Essentially none | Baby quilts that get washed constantly, budget projects | Cheap poly can beard and shift over years; can look less "authentic" |
| Wool | High but light (warm, resilient) | Minimal | Bed quilts, show quilts where stitching pops | Price; a few people are sensitive to it; store carefully (moths) |
| 80/20 cotton-poly | Low-medium | Mild (1–2%) | The all-rounder — most modern quilts | Nothing serious; the closest thing to a default choice |
| Bamboo / silk / blends | Silky drape | Varies | Special projects, luxury gifts | Price and availability; check the stated quilting distance |
Shrinkage Is a Feature, Not a Bug
Many quilters choose cotton for its 3–5% shrinkage: washed once, the quilt develops soft puckers around the stitching — the cozy vintage look people associate with heirlooms. If you want that effect, don't pre-wash the batting. If you want a flat, stable quilt (say, a wall hanging), cotton that's been pre-shrunk, or poly, is the safer pick. Our quilt washing guide covers how to wash so the shrinkage stays charming rather than damaging.
Quilting Distance: The Number Beginners Miss
Every batting package states a maximum quilting distance — how far apart your stitching lines can be. Low-loft cottons often demand 3–4″ spacing; some polys allow 8–10″. This matters more at the design stage than people expect: a big-block quilt with widely spaced straight lines pairs poorly with a batting that demands dense quilting. When in doubt, quilt closer than the maximum — dense quilting is never the thing that ruins a quilt.
What a First Quilt Should Use
Our honest recommendation, and the one most quilting teachers give: an 80/20 blend, or a low-loft poly, in a crib-size package for your first throw quilt. Both are forgiving under a walking foot, inexpensive, and behave well with the straight-line quilting a first nine-patch uses. Skip wool and specialty battings until machine quilting feels routine — their virtues shine with free-motion work you haven't learned yet.
