Here's what Paintbrush Studios says: "You shouldn't have to settle on your solids. We heard your feedback on the current leading fabrics on the market, and designed the Painter's Palette line to outperform the competition and solve your problems. Here's how- A Better Basecloth - Our unique fabric composition ensures less fraying when cutting and less warping when washing. Our solids resist bleeding and fading, protecting your quilt from the first wash and whatever comes after. Color You Can Count On - Designed for precision quilting, our solids provide grip without sacrificing softness. The Right Handfeel - A quilt represents a major commitment of time and energy, and an investment in the best materials keeps your project looking its best for years to come."
Paintbrush Studios says Purple is a color match for Kona Cotton Solids #477 Heliotrope.
Aurifil Thread match is 2520 Violet.
