Look at the repetition both of the vertical elements and the diagonal elements in this piece:
|Five Mills Rampant|
In cartoons, the artist uses lines: skinny curved lines around the object that is moving - havn't ever seen that done in a quilt! but I'm sure it would work.
Also, notice that a usually vertical object is horizontal - i.e. his ears. We often see this on pictures of flags:
You can almost feel the wind that has this flag furling out across the deep blue sky.....
And while I've not made a quilt with a flag - you can see the same effect with smoke in this quilt: Oh, What Pretty Smoke!
Do write and let me know your favorite techniques for showing movement - and also comment on which of the above you think is the most effective...your first impressions are very important!
And, if you have been, thanks for reading!
