Discover the Petra Prins Collection of 60 wt Cotton Threads

WonderFil® has partnered with celebrated Dutch fabric designer Petra Prins to launch a unique thread collection featuring 60 wt cotton threads. Designed to perfectly match Petra's timeless quilting fabrics, this collection brings together beauty, quality, and functionality in one elegant package.

What Makes 60 wt Cotton Threads Ideal for Quilting?

Efina™ threads are made from 100% long-staple Egyptian cotton and are double-gassed for an ultra-low lint finish. As fine, 60 wt cotton threads, they deliver smoother stitches and flatter seams, perfect for precision work and delicate quilting techniques. Whether you’re hand stitching or using a machine, Efina™ ensures a clean, polished result.

Threads That Coordinate Seamlessly with Petra Prins Fabrics

These color packs are curated to pair flawlessly with Petra Prins’ signature fabric lines. From rich heritage hues to fresh pastels, the Efina™ blend beautifully with her designs, allowing your fabric and piecing to shine.

Ideal for Hand and Machine Sewing Techniques

These packs offer versatility across various sewing applications:

• Hand piecing

• Machine piecing

• Needle-turn appliqué

• Fine detail quilting and topstitching

Because of their strength and thinness, they are especially effective for high-precision work and layered stitching without added bulk.
