Bloc Loc’s Flying Geese 1″ x 2″ ruler locks onto seams for instant ruler placement, total control so that the seams end in the corner and trims the correct amount across the tip. Ruler rock is gone, too! Once the unit is completed and trimmed, it will measure 1 1/2″ x 2 1/2″. Trims full & partial flying geese, parallelograms, square in a square and many, many other versions of flying geese units.
