Conductive fabric ($16.25 line/ft)
(You can buy the small size of “Zelf” conductive fabric from Less EMS)
Several pieces of felt (1inch x over 10 inch)
a pair of scissors
1. Cut the conductive thread 1/8 inch width.
2. Attach two pieces of conductive thread on the felt separately using fabric glue to make two lines.
* When you connect two separate pieces of conductive fabric to make one line on the felt, you need to tie the edge of the pieces together to prevent to loose continuity.
