I have some thoughts on the tee shirt design and hope I don't hurt any feelings.
The designs, as shown in the ship's store need some work. It looks to me like the design, as is, should be reduced in size and placed as a chest patch on the front. The design would work well on the back but would need to be enlarged for that application. It could also be just enlarged and left on the front but normally large designs don't look all that good on the front, at least to my eye. As it is, the designs look a bit lost and out of place.
