FAQs - Frequently Asked Questions
What’s the difference between 40wt and 12wt Aerofil?
40wt is a versatile, medium-weight thread great for piecing, quilting, and sewing. 12wt is thicker and stronger — perfect for bold topstitching, handwork, or decorative stitching that stands out.
Does Aerofil produce lint?
Very little. Aerofil is engineered for low-lint performance, producing significantly less buildup than most cotton or rayon threads. While no thread is completely lint-free, Aerofil helps keep your bobbin area cleaner — especially during long quilting sessions.
Is this thread suitable for quilting and sewing?
Absolutely. Aerofil is designed for both—strong enough for quilting through multiple layers and refined enough for garments and decorative stitching.
What makes the supersize spools special?
With 1000m of thread and dual thread locks, supersize spools reduce waste, storage mess, and spool changes.
