# NeoPixel LED Cortana Costume
## Overview
http://youtu.be/LxMiDvhkTXs
In this project we’re adding sewable NeoPixels and GEMMA to a bodysuit to make a light up Cortana costume.
To get extra details, we’ll trace artwork from reference photos, format the artwork and make a stencil that we can 3d print.
### How it Works
This sewable project uses a Gemma, NeoPixel Rings and sewable NeoPixels use our condutive thread to connect data, power and ground.
### Project Advisory
Stitching on stretchy fabric can be very challenging. Be sure to stretch the fabric while you sew so the thread doesn’t end up too tight, or the strong stainless steel thread might tear the fabric. If you’re a beginner, stick to soldering or try an easier conductive thread project first!
