Neither do I.....and it hasn't made a hoot of difference for me....

As a long time garment stitcher I've always tried to keep the grain as it should be. However for small pieces I don't think it's that big an issue. If I'm doing something where it will look better if the print matches, then I try to accomplish that. Bias does not intimidate me and I usually don't have too much problem with it.

agree with skitti1321. Don't have a problem stitching on stretchy edges and gives me a lot more freedom in my cutting.

If you use Nifty Notions (and other comparable) HSQ rulers you can save fabric and keep outside triangle edges on straight of grain. But sooner or later you are going to have to deal with a bias edge.
