Mac Folders Question

[Leah]

On my PC, I kept everything in neat little folders. When I would open the folder, I could view all the thumbnails and could see what I needed.

But with my Mac, I've still got folders, but when I open them up, I can hardly see each thumbnail, they're so tiny! I've figured out how to increase the size, but then it makes my window all slidy and I don't want to have to slide back and forth to view my thumbnails. I've tried decreasing the grid (the space between each thumbnail), but it only goes so far. Is there another way that I can customize within each of my folders for easy viewing (specifically scrapbook paper and embellies)?
