I have it and I really enjoy the book. I haven't felt up to the night gown challenge, but I have made both dischloths numerous times, the absorba bath mat, the baby kimino, and a few of the bibs. It's fun reading too. You lucky duck to see the authors, they don't seem to come to the west coast.
Visit their site www.masondixonknitting.com. On the R hand side about a 1/4 of the way down you can click on their knit-a-long and see projects people have done from the book. Some people have produced some exquisit things, there are lots of archives in the knit-a-long. No one has posted a night gown though.
I would recommend the book but I know some people don't like it. There isn't much in the way of clothing, more homey things. But homey things always fit.
