If you would like to try this, check Amazon for the book listed in my last post about halfway up this page. Because of copyright laws, I can't just give you explicit directions. It's a paperback and pretty cheap. I just bought a used one. I started this with the scant directions the gal gave that was doing the demonstration, but I was sure glad I ordered the book as I got further along.
Today I was looking at the new Star Quilts book I had purchased and it gives the directions for the way you were talking about.
