Use a multimeter to test a variety of conductive thread and conductive fabric for continuity and resistance. Esty vendors aajan29, Urbanstein and OhmSpun as well as Mitsifuji and some unknown manufacturers products are tested for use in wearable computing eTextile prototypes.

Recommendation – only purchase conductive thread from a vendor that states resistance in ohms/foot.
