Here’s How I Turned Myself into a Goniometer for Halloween

This year, a PT coworker and I schemed a duo costume for ourselves at the last minute. She was a lower body goniometer, and I was an upper body one!

If you’re ever finding yourself needing to dress like a goniometer in the future, here’s how I made my costume.

Step 1. Get a white t-shirt.

The reality is, I could have grabbed a men’s long sleeve t-shirt from Walmart for around $7. But my Walmart didn’t have any in stock, and shipping would have brought it to around $15…. so I ordered this 2-pack from Amazon.

Step 2. Create the circular center of the goniometer.

I just cut out a circle from the cardboard side of the Amazon box the t-shirts came in (tracing my largest mixing bowl to get the perfect shape). Then I glued a piece of white paper onto the front of the cardboard circle. And finally, loosely drew the degree makers around the edge of the circle.

It’s important to remember that we’re not looking for perfection here; we’re having fun and making it look generally like a goniometer!

Step 3. Add the measurement markers to the sleeves of the shirt.

Similarly to my actual goniometer, I only drew a single line on one sleeve, and then a line with some ruler markers on the other.

Step 4. Attach the circular center of the goniometer to yourself/the shirt.

If I had the time to use Velcro pieces to attach the cardboard circle, I probably would have done that. But this was last minute and I was going for ‘simple-easy-with-things-I-already-own’ tactic. So I attached two “straps” made of twine to the back of the cardboard using tape.
