See the 4 logo ideas in the jpeg. Remember, it's a logo for baby bed sheets and blankets.
I like the look of the Green Mill. I like the colors and the natural feeling of nature that it evokes. I also like the background watermark circles since it looks like fabric a little bit... but that may be better on packaging than on the actual logo itself?
I also like the look of this circular design with the 2 hills and the lonely tree, but with a little windmill instead. Even the way the image has a look of fabric to the design is interesting (that scratchy effect).
Perhaps my favorite, because of simplicity, is the 'baby birds' and 'habitat baby' logos. They are simple and I like the soft, baby colors. If you could incorporate a cute little windmill and make it look like the 'habitat baby' logo, that might work well.
If you can (and it looks ok), maybe create a 'baby-ized' version of a windmill if possible... you know, how there is a regular vector of something and then a baby-ized version? See the pic to see what I mean.
I would perhaps like for the windmill to look like something that seems 'cute' and could potentially be brandable on clothing in the future. In other words, not like a vector image of a regular old windmill, but a cute 'baby-ized' version. Make it look fun. Make sense?
