Frequently Asked Questions
- Why choose cotton thread over polyester at all?
- Matte organic finish, seamless blending into cotton fabric, biodegradability, and the traditional character heirloom quilters want — polyester's sheen and hand simply read differently.
- What's the all-cotton sandwich?
- Cotton top, cotton thread, cotton batting (Tuscany, Warm & Natural, QD Select Cotton), cotton backing — the most unified traditional construction, and how heirloom quilts were historically made.
- What's the longarm tradeoff?
- Cotton breaks more readily under high tension and sheds lint — slightly slower, cleaner-machine-required running in exchange for the matte natural stitch.
- Is it good for machine appliqué?
- Yes — on white and light fabrics, cotton thread gives appliqué the matte, needle-turn-adjacent look polyester can't fake.
- Cotton white or poly white for wholecloth?
- On cotton wholecloth where hand-crafted character is the goal, cotton thread. Where you want luster along the design lines, White Glide.
