I believe BearPaw is making strips for applique, not binding. Yes , straight binding is usually better for quilt binding, but should be bias for going around curves.
JoANN's YOUR GUIDE TO QUILTING has GREAT pictures and directions for doing bias tubes for applique, ,AND further back in the book,the continuous bias long strips.. It does take some study and trial, but you have to OFFSET the lines by one mark/line you have drawn, and THEN cut on lines to make LONG bias strips.
