Yes. You can sew cotton fabric with polyester thread for most everyday projects. Major manufacturers describe general-purpose polyester as ideal for garment construction across a range of fabrics, including light cotton; for quilting, cotton thread gives a classic matte look while polyester is often chosen for durability and strength (Singer thread collection).

When polyester thread makes sense on cotton

Everyday garments and home textiles that see frequent wear and washing. Polyester is strong and durable for general-purpose sewing (Singer thread collection).
Projects where color retention and abrasion resistance matter. Polyester typically holds color well and stands up to friction; cotton thread offers a softer, matte look (MaggieFrames: Polyester vs Cotton Thread).
All-purpose use on mixed-fiber wardrobes. Singer recommends general-purpose polyester for most garment construction across fabric weights from light cotton to denim (Singer thread collection).

When cotton thread is the better match

Visible topstitching or heirloom details where a traditional, matte finish is desired. For machine quilting, 100% cotton thread gives a classic look that blends well with cotton fabrics (Singer thread collection).
Projects where you want to minimize sheen. Polyester can appear slightly shinier than cotton (MaggieFrames: Polyester vs Cotton Thread).

Set up for smooth results on cotton with polyester

A few simple checks help polyester stitch cleanly on cotton:

Match needle and thread to your fabric weight. If you are unsure about needle sizing, see What needle size should I use for different fabrics? For general guidance, manufacturers advise pairing thread weight to fabric weight (Singer thread collection).
Thread the machine correctly and wind the bobbin evenly to avoid tension issues. If thread breaks, common causes include low-quality thread, incorrect tension, improper threading, or a dull/wrong-size needle (Singer thread collection).
Sew a short test seam on scrap cotton to confirm stitch balance and appearance before final seams.

Quick pre-sew checks for polyester thread on cotton

Install a fresh needle that suits your cotton fabric and thread weight
Wind and insert the bobbin evenly; rethread the top path carefully
Sew a 4-6 inch test seam on scrap cotton; adjust tension if stitches loop or pucker
Evaluate finish: choose cotton thread if you prefer a matte, traditional look

Common issues and quick fixes

Thread breaking: Recheck threading, use a quality thread, match needle size to fabric, and fine-tune tension (Singer thread collection).
Loops under the fabric: Usually upper tension or threading related. See Why there are thread loops under your fabric when you sew for step-by-step fixes.
Puckering or an overly shiny topstitch: Lengthen stitch slightly, try a finer needle, or switch to cotton thread for a lower-sheen finish (MaggieFrames: Polyester vs Cotton Thread).

Bottom line

It is absolutely okay to sew cotton fabric with polyester thread. Choose polyester for strong, colorfast, everyday seams and choose cotton thread when you want a traditional matte look, especially on visible quilting and topstitching. Test on a scrap, match your needle and thread to the fabric, and adjust tension for clean, balanced stitches (Singer thread collection; MaggieFrames: Polyester vs Cotton Thread).
