I don't often make things that would benefit from fringe, but the last couple times I have, I've done it a little differently than normal.  

I really like the look of using a contrasting yarn for fringe rather than using the same yarn as was used in the body of the project.  It's a fun way to use a novelty yarn or just a contrasting color, and the juxtaposition of contrasting colors or textures can really make the whole piece more visually interesting than a more conservative approach without being garish.  I really like how the contrast frames the design of the piece, rather than drawing attention away from it.
