I got this book solely for the lounge pants pattern. I have made those lounge pants, at least, 10 times now - for me, friends, family, etc. These are seriously the most comfortable lounge pants I have ever come across - plus, they're easy to sew.
As for the other patterns, in truth, I haven't made any of them. The book is beautifully photographed, the instructions are clear, and the patterns look enticing. I just haven't found the time to really make anything else. My sewing time is limited, so I make only what I need. I'd definitely love to make a few of the other patterns eventually, though.
