I've only made two lone-stars (one is incomplete) ... I paper-pieced them. the diamonds are roughly 1/4" wide.
You CAN paper-piece lone star. You piece one blade at a time, one row at a time. Your PP paper needs to have a smudge over 1/2" "blank" line between each of the rows. After you fill the blade with all of your diamonds row-by-row you then "fold" the blank and sew along the lines of rows to join them into a blade. Then you join all the blades.
