We found this last summer on a trip to Canada and have fallen in love with it so much we thought you would love it too.  The 3 sided shape makes freehand curves easy for laying out seamlines.  The think edge makes strong, sharp lines.  4 colors offers you the flexibility to choose the color with the most contrast.  The lines disappear with some light rubbing or a damp cloth.
