Plastic Bobbin of Conductive Thread - 30'

Replacement:DEV-10867. We now carry a new conductive thread on 60' bobbins. This page is for reference only.

This is 30ft of high quality 4-ply conductive thread on a clear plastic bobbin. Use it to sew up all of your e-textile projects. We created this small bobbin to help people get into wearable electronics without the upfront cost of buying an entire spool of thread. 30 feet of thread is enough to get a simple design stitched onto your shirt, backpack or hat.

    What are the specs on the plastic bobbin?

    • MTMentat / about 11 years ago / 2

      From the comparison picture with the quarter, the diameter of the bobbin is approximately 3/4" making it likely that it is either a Class L or Class 15 bobbin. The height of the bobbin is approximately 1/2 the diameter from the first picture (~3/8"), so my best guess is that it is an L-Class bobbin. It's probably made out of PET plastic, so don't expose it to temperatures over 75C (165F) or you'll go past the glass temperature.
