Interesting story with part of this jacket. The yellow fabric on either side of the collar came from a piece of gortex-like fabric that had a logo on it. The logo was for something (either a team or a company) that I did not recognize.

The challenge was that I had only about 1 foot suqare of that fabric and the logo was in the center.

I met the challenge by keeping these pieces small yet symetrical. I made up for lost space by adding the black edges adjacent to the sleeves.
