If you want to be totally blown away by what can be done with knitting, check out this:
http://mygreenweddingdress.blogspot.com/. A bride is knitting an incredible lace train for the wedding dress she designed. I've been enjoying watching her progress since seeing her mentioned on the Mason Dixon site. When I think a project is too huge, I think about what she's doing. I was a crazy bride - I made my own dress and all the bouquets - but never in a million years would I have taken on this project. (Maybe that's not true - I didn't know how to knit back then).
