Question 1

What weight sewing thread should I use?

Accepted Answer

Use 40wt-50wt all-purpose thread for most garment seams and machine sewing; it disappears into the stitch. Drop to 12wt-30wt for topstitching, hand quilting and visible mending, where you want the line to show. Go up to 60wt-80wt for fine seams, piecing and lightweight fabrics. Remember the scale is reversed: a smaller number is a thicker thread.

Question 2

Polyester or cotton thread — which is better?

Accepted Answer

Polyester is the strongest, most flexible all-purpose choice and the safest pick for knits, synthetics, activewear and anything that needs give. Cotton thread is preferred for quilting and natural-fiber wovens because it presses flat and matches the fabric's fiber. A good rule: pair cotton thread with cotton fabric, polyester with stretch and synthetics.

Question 3

What is serger thread and can I use regular thread instead?

Accepted Answer

Serger (overlock) thread is finer than standard thread — typically Tex 21-30, around 40wt polyester — and wound on large cones of 1,000-6,000 yards because a serger uses 3-4 threads per seam. The finer build cuts bulk while the multi-thread seam stays strong. Regular spools run out fast and add bulk, so dedicated cone sets are worth it for frequent serging.

Question 4

How much does a spool of thread cost?

Accepted Answer

A standard all-purpose spool typically runs $3-$8, with premium cotton, silk and bonded nylon spools $6-$12. Large serger cones and curated color packs from makers usually land between $15 and $45. Hand-dyed and variegated artisan spools sit at the higher end of the spool range because they're produced in small batches.

Question 5

What thread do I need for hand quilting versus machine piecing?

Accepted Answer

For machine piecing, use a fine 50wt-60wt cotton or cotton-covered polyester so seams nest and press flat. For hand quilting, choose a heavier, often glazed or coated 28wt-40wt cotton that resists tangling and shows a defined stitch on top. Many makers list variegated and hand-dyed cotton specifically for visible hand stitching and sashiko.

Question 6

How long do thread orders from independent makers take to ship?

Accepted Answer

Stocked spools, cones and color packs generally ship within 2-5 business days. Small-batch hand-dyed, variegated or custom-blended thread can take 1-2 weeks since it's dyed to order. Check each listing's processing time and bundle quantity, and message the maker if you need a specific color matched before a project deadline.
