Making rosettes is so easy using the MS Score Board.
I follow these directions step-by-step and it works for me everytime!
**cut a strip of paper 12 inches X 1 1/4 inches (the rosette will be double whatever width you make the strip...experiment with 1/2 inches, 1 inch, etc). This will make a 2 1/2 inch rosette.
**lightly tape two edges of the paper strip to the top of the score board (use removable tape, if possible, because you will be taking the tape off)
**then score the paper strip at 1/4 inch intervals all the way to the end
Special word of caution here...the Martha Stewart Score Board has a slight gap between the left edge of the ruler and where the measurement actually begins. Please make note of this, or your scored strip of paper will not be uniform!
