Pin connections and Arduino IDE pin control numbers. Flora follows the Arduino Leonardo pin numbers for SPI: MISO, MOSI, and SCLK which are on Flora's ICSP area (the six holes inside the circle).

You can see there is only one digital pin left (TX/D1) if the Neopixel and IR control are used. That is fine for this project, if you wish to add more, the TX pin could be used to time additional Neopixels for example.
Above is the wired circuit, ready to install in the costume.
