Samples and Examples

I just sort of took a couple of the images and put them on mugs so we could all see what they would look like...they look kinda crooked to me, but I think it's because the mug is round or something because the images aren't crooked and they should be on there straight (they're straight on the t-shirt). I guess the right thing to do would be to put these up and then order one for myself so that I can see the quality...should I bother? Has anyone gotten stuff off CafePress? Is it OK or do I need to check my work? Also, now that I see them like this they look kind of plain to me. Damnit...I just don't know if creatively speaking I have it in me to make them any fancier than this. Sheesh, this is harder than one would have thought (if one had been thinking, which, as usual, one was not).
