I choose and ill fitting bra and placed the sensor in the triangle between the cups, where it didn't touch my skin.
I moved it! Simple, I know, and barely worth saying, but the sensor location isn't something I considered past the ease of setting up the circuit, figuring that the bra touches my skin pretty much everywhere.
Since it didn't touch my skin, it was more exposed the air than it was to me. The pocket created between my skin and the bra was warmed than regular air, but not by enough of a margin that the sensor was good at distinguishing.
To remedy this, I moved the sensor between the triangle between the cups to the inside of the cup on my right. This seemed to work well, and I was a little nervous to move it again and mess anything up.
This probably doesn't work as well, because as you might know, boobs are mostly fat, and I am not sure if anyone else has noticed this, mine tend to be colder underneath than the rest of my body. I used a long line bra, which is like a regular bra, but it has support boning going vertically down the band.
If I were to do this again, I would move the LilyPad up and put the temp sensor below it, so no matter what it would be against my skin in a warmer spot on my body.
Cheap conductive thread is really itchy on skin!
I was gifted really nice conductive thread! Its soft and silky, and it is some kind of magic witch craft. Unfortunately, I did all the stitching with the cheaper stuff, and i was not about to take it out, because stitching the LEDs in took forever - so, I ended up gluing a layer of fabric onto the top, which worked well.
* I saw my solution because this is by no means the only solution, but it is the one that worked best for my skill and my project. (:
If you wear the wearable with the conductive thread next to your skin while it is programed, it gives you a nice little shock! Nothing jolting, just enough to notice.
I had not noticed this before with other wearable projects, but they also were not in such sensative areas of my skin.
Questions I got:
Q: Isn't the LilyPad uncomfortable?
A: Not at all! It feels no less comfrotable than a zipper. The thread on the other hand...
