E-textiles: Custom Design Cushions with LED Lights

etextiles_pillowcase-320_smallA group of young fashion engineers gathers on Saturday afternoons to design and create e-textiles; bracelets, soft toys or other accessories using conductive materials and LED lights. The design process starts with thinking about the functionality of the creation; Which materials will be needed and how to assemble everything together.

Items needed vary depending on a project. For these custom design cushions we used the following: felt fabric in different colors (from amazon.fr),  sewable LED lights (from Kitronik), conductive thread (from Kitronik), 3V Coin cell battery holder with the latch (from Kitronik or Lilypad), 1 x CR2032 Coin Cell Battery and filling (organic wool from amazon.fr).

We first designed the cushion’s artwork, then cut the patterns from a sheet of felt and sewed them on another sheet of felt (in this case size of a sheet was 30x30cm). Secondly, we decided where the LED lights should go and designed the circuit. It’s good to test if all the components function by connecting them with the crocodile clips. Thirdly, we sewed the components on the cushion with the conductive thread. Make sure to do it right – check the Sparkfun Tutorial on Conductive Thread and Conductive Thread – 10 Tips Youtube video by Adafruit Industries. Lastly, we stitched together the patterned felt sheet and a blank one leaving a small opening for the filling on one side and closed the opening when the cushion was nice and puffy.
