I'll be honest. I made a lot more progress than I thought I would. Here are two small chunks of Tycho's shirt:
The first chunk is part of the neckline. The blue will extend down past the bottom of the arms, and meet up with the large light blue stripe. Sleeves will attach to the angled edges with 45 degree seams.
This second chunk shows off more of how the shirt will look in the end. The lowest blue stripe makes the bottom 'seam' of the shirt with the stripes running horizontally across the torso.
No promises on how often I'll update with this project, but I will take photos whenever I have something awesome to show off.
