Horizontal Tile: This background was created with the idea that the Ice Cream is Moolicious! Get it? Moolicious Ice Cream... Yea, so the pink color gives it a fun presence for kids who would be viewing the site. With navigation in pink, perhaps a theme could be made out for kids.

Vertical Tile: This background has the theme of clouds on a blue sky because I feel that's the calming theme for a sweet and endearing cow. When I thought of Molly Moolicious, I thought of funky clouds, like she were in a pasture under this kind of sky. Not to kiddish for adults, but fun enough for a kids imagination.
Image: Again, the pink is for kids and since this is a female cow, I think it fits. A simple profile of the head of a cow is meant to be Molly Moolicious. As a background, it's not overpowering enough to cause problems with any text there may be. The image of the cow could also be converted to be used as a logo or icon for the company.

Patterned: A squiggle blob filtered with Tile Maker and then Kaleidescope makes this a fun background! Light enough to have text and to make the background not just a simple white.
