Frequently Asked Questions
- How does Aurifil 40wt differ from 50wt?
- 40wt is heavier than 50wt — it creates a slightly more visible quilting line. Some quilters prefer 40wt for decorative quilting where the stitching is meant to be seen; others prefer 50wt for a more delicate, nearly-invisible line. Both are excellent for domestic machine quilting.
- Is Aurifil 40wt appropriate for longarm quilting?
- Yes — 40wt is more commonly used in longarm machines than 50wt due to the closer weight match to standard longarm thread weights like Glide and Omni (also 40wt). Aurifil 40wt cotton provides a premium natural alternative to polyester longarm threads.
- What colors are included in the assorted set?
- Check the current product listing for specific colors. Aurifil assorted sets are curated to represent widely-applicable, popular colors across the spectrum.
- Is Aurifil 40wt cotton a good alternative to Glide polyester for longarm use?
- For quilters who prefer natural cotton thread, Aurifil 40wt cotton is the premium alternative. It has a different hand and appearance than polyester — more matte, more natural. Some studios stock both for different customer preferences.
- Is the assorted set a good introduction to Aurifil 40wt?
- Yes — ideal for trialing the 40wt weight and color range before committing to individual spool purchases.
