Guides for this decision
Read size before spool length
Several listings here identify #69 or Tex 70 bonded nylon. Another specifies a long spool without a confirmed numeric thread size in the collected information. Treat that missing size as a question to resolve, not permission to assume it matches the others. Spool length tells you how much thread is supplied; it does not tell you whether the thread fits your needle, hook or intended seam.
Test the complete thread path
Confirm that the machine is intended to use the selected thread and that the spool can feed through an appropriate stand without snagging. Evaluate top and bobbin thread together on the actual construction. The thread-size guide explains the labels, while the bobbin thread guide covers why the underside deserves its own setup check. Good-looking top stitches alone are an incomplete test.
Buy colors around finished projects
A color assortment can be useful for small batches, while repeated production may justify more of one shade. Compare the thread against the finished leather in the light where the item will be used; strong contrast makes small spacing changes easier to see. For outdoor exposure, review nylon versus polyester before choosing solely by color. Keep machine thread separate from waxed hand-sewing supplies, which should not be presumed suitable for the machine's tension and hook system.
