Buying Guide
What should you consider when buying 100% cotton thread?
- Fiber quality: Look for long-staple cotton and mercerized finishes for strength and sheen.

FAQ
- What is mercerized cotton thread?
Mercerized cotton undergoes a chemical treatment to increase luster, strength, and dye uptake, producing a smoother finish with less lint. - Is 100% cotton thread suitable for all fabrics?
It works well with natural fabrics like cotton and linen. For synthetics, consider blends or polyester threads. - How much thread do I need per project?
Estimate yardage based on fabric type and project size; quilting typically requires more yardage than garment making. - What is the difference between 30WT and 50WT?
30WT is stronger and thicker, good for dense seams; 50WT is finer, better for delicate stitching and detailed quilting. - Are these threads suitable for hand sewing?
Yes, most 100% cotton threads work well for hand sewing, but check the ply and weight to ensure smooth threading and even stitches.
