For longarm machines, AeroQuilt is the thread designed for the job. It's a strong 100% polyester built to handle high-speed quilting without thread breaks or excess lint, with a soft sheen that looks great on both detailed and edge-to-edge work. It comes on large 3,000-yard cones, so you can finish a full quilt top without stopping to re-thread or risking a visible join.

Cotona (cotton) and Aerofil (polyester) are both excellent — the right pick depends on your project. Cotona is 100% long-staple Egyptian cotton with a soft, matte, natural finish that blends beautifully into cotton fabrics, making it ideal for heirloom sewing, detailed piecing, and traditional quilts. Aerofil is a strong, low-lint polyester that's colorfast and flexible, great for all-purpose sewing, garment construction, topstitching, and precision quilting. In short: choose cotton for a natural look and feel, polyester for maximum strength and durability.

Thread weight affects how visible your stitches are and what the thread is best suited for. Lower numbers are heavier, thicker threads; higher numbers are finer. Cotona's fine 50 weight is ideal for detailed piecing and machine quilting where you want the thread to blend in, while AeroQuilt's 40 weight suits general quilting and free-motion work. If you want the quilting stitches to stand out as a design feature, choose a heavier weight; to keep them subtle, go finer.

Both Cotona and Aerofil work beautifully for piecing. Choose Cotona if you're working with cotton fabrics and want a natural, matte thread that disappears into your seams; choose Aerofil if you want extra strength and durability, especially on seams that will be washed and used often. Both are fine and low-lint, so they produce clean, even stitches without bulking up your seams.
