As often happens, I'll be mulling over an idea or concept and, while I'm not looking for it directly, other related ideas or applications will pop into my field of vision from a variety of different sources. In this instance I checked a knitting book out of the library. It deals with knitted embellishments and I got it mainly because I like the author's other books and it has flower designs in it. I've been on the hunt for those lately. However, there are actual working patterns for several Celtic knots right in the middle of the book.
I'm not sure exactly what I plan to do with this knowledge, but rest assured it will be used for good as art and not for evil.
