Apparently I'm feeling a bit silly tonight - thought it might be fun to put paws and treats (like milkbones) in the centre of the stars ...
In the background of the star points, you could do u-turns - in opposite directions so it ends up looking like a basketweave, and leave the star points unquilted so they puff out. If you do the u-turns so they are very close to the star point edges, it would be like SID - defining the point.
This is a very horrible drawing using paint ... cannot draw with my mouse!
