Who wants to be a robot? OK, now, who wants to be a robot that lights up?

This child’s hoodie features LED lights in the control panel that can be easily switched on and off and also removed for washing. For a little extra light-up action, knit the control panel and the sweater’s I-cord edgings out of glow-in-the-dark yarn. Corrugated sleeves provide that Cold War robot chic. What a great way to light your path of mechanical mayhem on Halloween or any other day of the year.

If you’re like me, then knitting a costume for Halloween seems crazy for two reasons:

  1. the idea of knitting something that will be worn once pierces you to the core
  2. your kid does not always like to call attention to him- or herself

This sweater is ideal for you then, because in the daylight, with the LED lights taken out, this looks like a regular hoodie. It can therefore be worn year-round and only signals its secret robot identity when and if the child wishes.

Construction of this sweater is simple and suitable for advanced beginner knitters. Let’s start assembling that robot!
