Looking for a quick LED project on something other than paper? Try sewable LEDs on a t-shirt.
- any t-shirt
- Embroidery hoop
- Conductive thread
- Battery holder
- Coin battery (CR2032)
- LED sequins
- Sewing needle (Make sure is small enough to fit in the eye of the battery holder and LED sequins)
- Test your LED sequins first with alligator clips.
- As you can see from the picture, I used the pocket of the t-shirt. If you are working with novices, I’d recommend you not use the pocket because it got a bit tricky avoiding sewing the pocket shut.
- Have teens design a picture on paper to plan where they are going to place the LED.
- Keep in mind that one side of the LED must connect to the positive side of the battery holder and the negative to the other side. This means two different tracks. I found using one sequins is best for novices.
- TIP-It’s best to draw a picture that has a mirror image and then place the sequins in the middle.
- Have teens lightly pencil draw their picture on the t-shirt. This is to keep their sewing straight. Remember to hold a place for the sequins.
- Thread your needle. Don’t double thread like you do traditional sewing thread. It will be too thick. In other words, don’t pull your thread through the eye of the needle to create two strands of thread like traditional threading.
- On the under side of the t-shirt, secure one side of the batter holder by looping through three times.
- Sew your track to your sequins.
- IMPORTANT!!! Make sure the positive side of the sequins faces the positive side of the battery holder.
- Begin a new line of thread for the other side of the battery holder and repeat.
- Insert the battery and cross your fingers that it works.
If your LED doesn’t work:
- Make sure you have a good battery.
- Be sure your threads don’t touch. This is usually the problem.
- Make sure your sequins +/- lines up with the battery.
