How strange - I had stumbled onto the website for Sylvia's Bridal Sampler quilt just this morning before coming here! The slide show is a lovely way to see the blocks as the pictures are excellent.
I don't have this book, but have Jennifer Chiaverini's other pattern books and they are very complete, so can't imagine that this one is any different. If you want to make a certain thing, and need the pattern, then the investment is worthwhile. It seems to me that it would be a good source of block patterns, too, even if you didn't make the whole quilt.
