Tatted Rings Headband

I was researching Tatting techniques online and I found this delightful little pattern using a technique called lock stitches.  This pattern is copyrighted by Gina Butler, here is the website for the pattern: http://ginabea.com/docs/Utility_Lock_Chain_Headband.pdf

I thought this would be a great way to pratice the lock stitch technique and I plan on giving the headband to my niece.
