Celtic Knots for Knitting

I think knitting patterns that includes Celtic knots, especially for repeating patterns, are a wonderful thing. Unfortunately, there don't seem to be that many. I found this one hat band, which immediately went into my project file. Then there was this trinity knot hot pad, which I found interesting since I have similar tattoed on me. But that seems to be about it.

On the upside, my "Enchanted Knitting" that I ordered showed up this week, and it has some nice patterns as well. I really want to get my hands on a copy of "The Tapdancing Lizard", but it was out of print for a while, and I need to let the credit card cool off. Anybody got a copy they want to sell? Cheap?
