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.  2 colors offers you the opportuntiy to try this great product with a small investment.  The lines disappear with some light rubbing or a damp cloth.
