Cotton Threads F.A.Q
What makes WonderFil cotton threads different from others on the market?
WonderFil cotton uses 100% long‑staple Egyptian cotton and is double‑gassed to remove 99% of lint strong, smooth stitches and cleaner machines.
WonderFil’s cotton threads are spun from 100% long‑staple Egyptian cotton. Mercerized and double‑gassed, they deliver a smooth, clean finish that reduces lint in your machine while producing consistent, premium matte stitches for quilting, piecing, and decorative work.
Which WonderFil cotton thread is best for quilting?
Konfetti™ and Tutti™ 50wt cotton are top for quilting soft hand, strong stitches, solids and variegated colors with a low‑lint finish.
Konfetti™ and Tutti™ 50wt cotton threads are favorites among quilters. Both use long‑staple Egyptian cotton, double‑gassed for low lint. Konfetti™ offers solids; Tutti™ provides variegated colorways that add depth to quilting and decorative stitches.
I use WonderFil cotton thread for piecing?
Yes. Konfetti™ 50wt cotton works for piecing, though DecoBob™ 80wt polyester creates flatter, more precise seams.
Piecing with cotton like Konfetti™ 50wt gives strong, natural‑looking seams. For the flattest seams and maximum precision, DecoBob™ 80wt polyester is often preferred because its ultra‑fine size reduces bulk and helps blocks align.
Is WonderFil cotton thread colorfast?
Yes, dyed to be colorfast and resist fading. Always test dark or saturated shades with your fabric before large projects.
WonderFil cotton threads use high‑quality, colorfast dyes that hold up to normal laundering. As with any richly dyed cotton, pre‑test darker shades with your fabric, especially for frequently washed items or those exposed to sunlight.
Does WonderFil cotton thread shrink?
No. WonderFil cotton is pre‑shrunk, reducing distortion after washing, safe for quilts and garments.
WonderFil cotton threads are pre‑shrunk during manufacturing to stay stable after laundering. This helps prevent puckering or seam distortion in quilts and garments and pairs well with pre‑washed fabrics.
Can I use WonderFil cotton threads for hand quilting?
Yes. Eleganza™ 8wt perle cotton creates bold stitches; heavier cotton quilting threads offer durability and a natural finish.
WonderFil offers multiple cotton options for hand quilting. Eleganza™ 8wt perle cotton produces bold, decorative stitches; heavier cotton quilting threads provide durability and a classic matte look. Choose the weight that matches your stitch style.
What needle works best with WonderFil cotton threads?
Use 80/12 for 50wt cotton; size up to 90/14 or 100/16 for heavier threads. A sharp or quilting needle gives clean results.
For 50wt cottons like Konfetti™ and Tutti™, an 80/12 universal or quilting needle works well. Heavier cottons or multiple layers may need 90/14 or 100/16. Sharp/quilting needles penetrate cleanly to prevent skipped stitches.
Do WonderFil cotton threads work well in high-speed machines?
Yes. Double‑gassed finish ensures smooth feeding even at high speeds. Adjust tension when switching from polyester.
WonderFil cotton threads are engineered for reliable performance in high‑speed sewing and quilting machines. The double‑gassed finish reduces drag and lint. When moving from polyester to cotton, a small tension adjustment may be needed—test on scrap first.
Which WonderFil cotton thread has variegated colors?
Tutti™ 50wt cotton offers variegated colors with gradual changes that add texture and depth to quilting and decorative stitches.
Tutti™ 50wt is WonderFil’s variegated cotton line, dyed to shift colors every few inches. It adds visual movement to quilting and decorative stitches and comes in many colorways to suit any palette.
Can I machine embroider with cotton thread?
Yes. Cotton gives a matte, traditional look. Use proper stabilization since cotton stretches less than polyester.
Machine embroidery with cotton threads like Konfetti™ and Tutti™ creates a classic, matte appearance perfect for vintage or traditional styles. Because cotton stretches less than polyester, use the correct stabilizer for your fabric and design to prevent puckering.
