I've been thinking a lot about white space lately and wanting to use it more in my art. I do tend to cover up a lot of the page, if not all, with color and marks. But I can see how white space is visually pleasing.
Eddy (like the eddies of ocean currents)
Egress (okay, now I'm really just pulling words out of nowhere - but seriously, wouldn't it be interesting to illustrate egress?)
Erstwhile (Have I been watching British period dramas or what?)
Eeek! (I'm thinking of a picture of a mouse inside it's little hideaway, tucked in bed with a piece of cheese)
Epiphany (that would be a fun one to illustrate)
Ewe (that makes me think of a song I heard as a child, goats eat oats and does eat oats and little lambs eat ivy, but I thought the lyrics were 'Goes ee dotes and dose ee dotes and little lambsy divey')
Look how interesting just a short one letter brainstorm can be! You can come up with all kinds of words and images and ideas to use for art.
