Kevin Flynn was a fun quickish build. The main fabric is a slubby upholstery fabric and it’s quite warm to wear. The tunic is polyester with a satin trim. From an interview with the costume designers, all the fabrics were synthetic. The electronics are two inch wide EL Tape from China (Aliexpress) and a matching inverter that is hidden in the identity disc holder. The identity disc itself is the licensed toy with new LEDs to make it white instead of blue.
