Okay, so I wanted to get a really accurate measurement of my underarm for a new shirt I’m making. I’ve messed this up before, so this time I was determined to get it right. Here’s how I went about it, step-by-step:

Getting Started
First, I grabbed my trusty fabric measuring tape – the soft, flexible kind, not the stiff metal one from the toolbox! I also made sure I had a mirror handy. It’s really tricky to do this solo without seeing what you’re doing.
The Process
- I stood in front of the mirror, wearing just a thin tank top. You want as little extra fabric as possible to mess with the measurement.
- Then, I lifted my arm just slightly – not straight up, but just enough so it wasn’t pressed against my side.
- I took the measuring tape and wrapped it around my underarm, making sure it went right into my armpit and around the fullest part of my upper arm/shoulder area. It’s kind of like where a t-shirt sleeve seam would sit.
- The tricky part was keeping the tape level all the way around. This is where the mirror really helped! I could see if it was dipping down in the back.
- I made sure tape is snug, I mean not tight and not cutting off my circulation.
- I looked in the mirror one last time to double-check everything was in place, then I carefully noted down the measurement.
My Recording
I actually measured a couple of times, just to be extra sure. I got the result.
It wasn’t as awkward as I thought it would be! The mirror was a lifesaver. Now I can finally make that shirt and know the sleeves will fit perfectly. Hooray for small victories!
