I agree...it doesn't matter really. I talked to a very well know show judge about this very issue. She said that she could never figure out where these ideas get started, but that if they (as judges) examined every quilt to look to make sure you didn't cross or hit another stitch line when stippling....they would go crazy!
Do you own thing, have fun and don't worry about it. You never know, you might come up with the next "great stitch design!
