This is the "Ball Decor" pattern in "Holiday Boutique Knitting".  The following are the results from using different yarns.  The sky is the limit with this pattern.  You could let the yarn do the work (like these examples) or add stripes or crystals or any pattern you choose!

 
You're welcome (for the free pattern) to all the people that belong to my Ravelry knitting group, "Holiday Boutique Knitting"!!  I am hooked on the ball decor and want to knit some white and navy striped ornaments, along with plain white with some added bling and plain navy.  There are so many ideas for a "nautical themed" Christmas tree!!
