Supplies:

• Nylon Fabric
• slightly stretchy knit fabric for cover (this is an aesthetic decision, but should be able to stretch with functional layer)
• non-conductive thread
• conductive thread
• conductive yarn with high resistance
• (2) lilypad Simblee
• 5v FTDI programmer
• 3 vibrating disc motors

// as you’ll need to refer to them in many other functions.
