I'm in a reflective mood (nothing to do with avoiding that stack of dirty dishes in the sink). I wasn't going to get into issuing challenges, because I think if there are too many, people will go crazy and just stop doing them. But I just created my 200th tangle pattern--I've gotta do something.

I love the idea that everyone who views my work, adds themselves to the mix. It's a different work for every single person who sees it.
