Fox. The thread was dyed by Tat-ilicious and was called "Young Hearts". It's a pretty mixture of greens, pale blue, brown and magenta, to which my scanner does not do justice.
My first tat was this Celtic picot motif from Jennifer Williams. I had seen Fox do it and wanted to try the new technique myself. It is more fiddly than exactly difficult.
Heart's Desire...however this is not a pattern to be made while watching television. This one is so full of errors I am ashamed to show it, except that sometimes it's fun for other tatters to enlarge and spot the mistakes. I am no longer sure how many there are, at the time it seemed to look awful, and now it looks ok. Bizarre!
