Step-by-step guide to making a sewable Halloween LED badge.
Step 2threading a needle with conductive thread guide. guide on starting to sew. Make sure the connection points are sewn tightly four or five times to ensure a good electrical connection. Once the coin cell holder is in place, run the stitches up through the alternating holes to where the LED will sit. Attach the LED in the same way you did the coin cell holder, making sure that the negative side aligns with the negative engraving on the badge, and making sure you sew tightly four or five times to get a good electrical connection. Finish the stitch off, if needs be refer to our guide, and cut the ends of the thread close to the components so no long bits of lose thread are left.
Sew through the alternating holes towards the LED as before.
Sew the positive side of the LED into place, as before making sure the connection is tight and well made.
Cut the ends of the thread off close to the components to avoid lose ends creating a short circuit.
Step 5fault finding section for tips on where you may have gone wrong.
Step 6Insert the safety pin from the back of the badge, through the top hole. Feed the safety pin down and and through the bottom hole. Keep feeding the safety pin all the way round until it's all the way back round to the back of the badge, and pin on to your clothes.
Step 7Find a suitable place to pose with your new badge, or alternatively find two willing workshop participants to do it for you!
