Cotton-Poly Blend (80/20) vs Cotton (100%)
A detailed comparison to help you choose the right batting for your quilting project
Quick Verdict
These two battings are close cousins. The blend offers slightly less shrinkage, slightly more loft, and a bit more quilting-distance forgiveness. Pure cotton delivers the classic crinkled look and maximum breathability. Many quilters have strong opinions about which is "better," but the truth is both are excellent everyday choices.
Side-by-Side Comparison
| Feature | Cotton-Poly Blend (80/20) | Cotton (100%) |
|---|---|---|
| Loft | medium loft | low loft |
| Warmth | 3/5 | 3/5 |
| Breathability | 3/5 | 4/5 |
| Shrinkage | 1-3% (subtle crinkle) | 3-5% (creates desirable crinkle effect) |
| Max Quilting Distance | Up to 6-8 inches apart | Up to 4 inches apart |
| Price Range | $$ | $$ |
Loft
The blend has marginally more loft than pure cotton thanks to the polyester content. The difference is subtle — you would notice it side by side but might not in isolation. Pure cotton lies very flat after washing, while the blend maintains a touch more body. Neither is as lofty as polyester or wool.
Warmth
Virtually identical warmth. The 20% polyester in the blend does not meaningfully change the thermal properties. Both are moderate-warmth, breathable battings suitable for three-season quilts. Choose between them based on other factors — warmth is not the differentiator here.
Shrinkage
Pure cotton shrinks 3-5%, giving you that pronounced crinkle texture. The blend shrinks only 1-3%, producing a softer, more subtle texture. If you love heavy crinkle, go with pure cotton. If you want just a hint of texture without worrying about losing size, the blend is your friend.
Price
These are priced very similarly — within a dollar or two of each other for comparable brands and sizes. The blend is sometimes slightly cheaper because the polyester content offsets the cotton cost, but the difference is negligible. Cost should not be a deciding factor between these two.
