Looks great.
To have a shirt ready in time for comic con I decided I'd draw the stripes and waves onto an existing shirt with a fabric pen, but I don't really know the correct spacing of the stripes. Did you find that out in order to make these swatches the correct scale? If so, can you tell me the spacing? Even with 2 weeks left until I wear the costume, it's going to be a mad rush getting the shirt finished, I expect it to take well over 20 hours to draw the whole pattern.
... do all the work to convert it ...
Where did you get the marker/what kind is it? I plan on buying a reissued blue shirt to replace the one I'm making now, but I won't spend that kind of money on the red. I will however spend a couple weeks drawing the red one no problem.
I'd still be interested in finding out the exact spacing of an original shirt. I've seen plackets on shirts everywhere from an inch to an inch and a half, so scaling based on that may not be 100% accurate.
