Photographs are a colour guide, not a guaranteed physical match. Screen settings, lighting and dye lots can affect appearance. Check your selected variant for current availability.
Care instructions depend on the shade’s dye group; not all solid colours share the same wash and bleach guidance.
Check your four-digit shade code against Aurifil’s colour and care guide, then follow the most restrictive instructions for the thread, fabric and batting. Test a stitched sample before washing the finished piece.

Yes. It is a fine option for patchwork piecing and understated quilting, as well as English paper piecing and appliqué. A heavier thread may be preferable when you want a more pronounced decorative line.
Compare a few shades with your fabric in natural light. Natural White 2021, Muslin 2311 and Dove 2600 offer different starting points; a short test seam is more useful than choosing from a screen alone.
A solid shade is designed as a single colour, unlike a variegated thread that changes colour along its length. Lighting, screen settings and dye lots can still affect perceived colour.
This is the 1300m large orange spool. Aurifil’s separate 5900m cone is a different format and is not supplied here.
Aurifil’s large spool has a removable base. Gently twist and remove it to release the thread end, then replace it before use.
Start with a quiet neutral or a confident colour. Match your fabric, plan your finish and keep the shade code close for next time.
