Function follows naivete.
I had a bra cup, so I made a kippah out of it.
I showed it to a rabbi, who said if she could wear it in front of her congregation, she would. I asked around about what this could possibly mean, and learned that women who are rabbis experience gender discrimination just like women in any other job.

I thought my intent was to make a feminine yarmulkes that more traditional women would be proud to wear, but as they came into creation, I discovered that they were for less traditional people who are bone tired of "traditional" men and their opinions.
