A detailed comparison to help you choose the right batting for your quilting project
Cotton is the tried-and-true choice with decades of proven performance and predictable results. Bamboo is the newer, eco-friendly alternative that offers exceptional softness and drape. For most quilts, cotton is the practical choice. For summer quilts, baby quilts, or projects where softness and sustainability are priorities, bamboo is worth trying.
| Feature | Cotton (100%) | Bamboo |
|---|---|---|
| Loft | low loft | low loft |
| Warmth | 3/5 | 2/5 |
| Breathability | 4/5 | 5/5 |
| Shrinkage | 3-5% (creates desirable crinkle effect) | 2-3% |
| Max Quilting Distance | Up to 4 inches apart | Up to 6-8 inches apart |
| Price Range | $$ | $$-$$$ |
Both cotton and bamboo are low-loft battings that produce flat, drapey quilts. Bamboo has a slightly silkier feel that makes the finished quilt feel more fluid, while cotton has a more structured hand. The visual loft difference is minimal — both will give you a thin, traditional-looking quilt.
Cotton provides slightly more warmth than bamboo. Bamboo excels at breathability and moisture-wicking, making it feel cool against the skin. For warm-climate quilters or summer bed quilts, bamboo's cooling properties are a genuine advantage. For year-round quilts, cotton's moderate warmth is more versatile.
Cotton shrinks 3-5%, producing pronounced crinkle. Bamboo shrinks 2-3%, with a softer, less dramatic texture change. Both shrink enough to create some texture, but cotton's crinkle is more visible and traditional-looking. If you specifically want the crinkled look, cotton delivers it more reliably.
Bamboo batting typically costs 20-40% more than comparable cotton batting. The premium reflects both the newer technology and the sustainability angle. For quilters who value eco-friendliness, the extra cost may feel justified. For pure value, cotton remains the better deal.
Bamboo's moisture-wicking and cooling properties make it ideal for warm-weather bedding.
Exceptionally soft against delicate skin, naturally anti-microbial.
The classic crinkled texture and proven track record make cotton the standard.
