To put that in perspective, I found a remnant of the blue and red jackquard fabric that was about 1/2 yard.
I used that remnant for two other shirts prior to making this shirt.
After completing this shirt, I had perhaps about 6 inches square of that fabric left over.
The light gree fabric on the back of my sleeves were from a 1/4 yard remnant that I purchased for less than 50 cents.
