I'm sorry to say I have not had an opportunity to try any of the patterns in this book.
I have used other Ellenor Burns books and have been VERY happy with the clear instructions. (I have only made two quilts, so I'm very much a beginner.)
To say you can make a quilt in a day, is only true if you are doing a baby quilt. My two quilts were for king size beds. I can't guess the number of hours I spent piecing, but I was very happy with how the quilts turned out (I did pay for the quilting, since they were so large).
I have take a couple of beginning classes on piecing and the instructor told me that virtually every quilting book has mistakes in them - not what a beginner needs to deal with. However, she has not found any errors in any of Eleanor Burns' books.
I anticipate many hours of enjoyment working with these patterns.
