I was flipping through some of my old sewing books a while back, looking for something (I can't even remember what) and was arrested by this image, which of course is the famous Walk-Away Dress:
If you can't read the caption, it is:
Even a beginner can make a dress like this one successfully, from two old dresses. This pattern is smart, adaptable, and easy to make since it only has a few pieces.
The book was Fashion Sewing on a Budget, and I have to say it's one of the more helpful of the ancient titles that I've accumulated. I think because it takes a "learning by doing" approach, which is the learning style I've always favored. (You make more mistakes, but you learn more from them!)
The online copies I've linked to above, on Amazon, are fairly pricey but my copy is marked "$1-" on the flyleaf and I'm sure I've seen this many a time in thrift stores and used book sales. Keep an eye out in those places, if you want it.
