Omak is correct. The technique is what's important. I'm going to eventually one day try this method in a miniature size so I won't be paying attn to the size she says to start with. It won't matter just as long as my strip pieced section is same width as my top layer which may be strip pieced also.
Since seeing this method, it has given me many ideas of trying other blocks with it which is what I'm most interested in.
Sure hope everyone will post pics of trying different things with this technique. We would love to see them!!
