The return of the inside-out jersey to Ballantynes went off without much trouble. The person who sold it to me looked at the front and back of the material, and agreed that the inside of it was the proper pattern that should be shown. But then she checked the existing stock and found that they all had the same issue. I explained about how it would require an inversion through 4th dimensional euclidian space to fix the problem, while she backpedaled saying that the jersey is how it should be. When I countered with “But the emperor has no clothes”, a full refund was then arranged.
The training of dad to use Sketchup is going well. After finishing off another model we moved on to using LayOut to create architect plans of it, complete with several different views (plan view, front view, etc…), dimensions of parts, and explanatory sections.
