A'Leigh, form comes more naturally to me, too. My wife is an artist. I like art, and between the two of us, I believe we have the two parts of a canvas. A canvas needs the wood and the canvas cloth on which to create the free-flowing art form. Form is necessary for freedom to have a place to express.
Play with your words. Bounce ideas against forms. Does the letter, "A" look red or blue or green to you? If you travel to a new class M planet, what landscape and environment would you find?
Imagine being a child playing with your food. Try playing with words like that.
If all else fails, then use a protractor to create fried egg flowers on art paper. Visual art often helps us to create word art. I hope this helps. Check out some of the photos on my profile. I do needlepoint embroidery pieces. Even though it is a strict form of art, it helps to unlock the artistic part of y brain.
