I've recently been bitten by the Celtic Tatting Bug, thanks to Rozella Linden.  I have been busy tatting all the Celtic type designs I can find.  Here are a few of them, more will be posted later.

Celtic Knot Tatting

This is Rozella's Celtic knot
Circle.  The thread is
size 10.

I have been teaching tatting at my local yarn shop.  My students want to learn Celtic Tatting as in Rozella Linden's new book, so I have been working all the patterns.  This is what I have done so far.
